AXE033
If you already have a serial LCD, the rest is easy.
If not, have a look at the AXE033. It costs a few dollars more than the parallel LCD but all the hard work is done for you. MicroZed are very quick off the mark with postal deliveries.
Is your starting point an 08M and a parallel LCD (as sold by JayCar and Altronics)?

With the AXE033 serial LCD as mentioned by inglewoodpete, there is nothing else required.
Have a look at the ACE033 datashsste here:
http://www.rev-ed.co.uk/docs/axe033.pdf
Also have a read of the SEROUT command in the PICAXE Manual 2 (v6.9) at page 173

Sarabande: Also consider old serial organisers & PDAs =>http://www.picaxe.orconhosting.net.nz/wizard.gif or => http://www.picaxe.orconhosting.net.nz/pvdemo.jpg etc, as their inbuilt serial terminal program works a treat with PICAXEs. Although now not as abundant as 5 years back, many of these still litter junk boxes & often can be yours for asking.
If you haven't got any LCD hardware, the AXE033 is the easiest solution, includes 2x16 LCD which is pretty much plug-in and go. If you already have an LCD, assuming it is HD44780 compatible, then FRM010 would be an alternative.
Both will work with a PICAXE-08M but LCD applications may require considerable storage to put text up on the display. Depending on what you want to do it may be worth considering moving up to the 18X or an X1 or X2.

Having worked with the FRM010 serial LCD driver chip (from Rev-Ed), I can say that route worked extremely well for me. It worked out the box (my own circuit and PCB) with a 20 x 4 Blue LCD from the East, no problem... consider it. Also as Hippy said above, maybe you will require a lot more memory (EEPROM etc also) for LCD text displays. It does take a lot of space...
Does anyone know if there's an SMD version of the FRM010?
I'd like some day to do a project involving the same sized screen as the uWatch and keep is as small as possible.
Sparkfun sell a serial LCD backpack which uses a SMD PIC for the interfacing, but I'd prefer not to have the hassle of desoldering it & re-soldering it on my own custom board, including working out its pinout.

Haku:
The FRM010 is only a PICAXE-18M (PIC16F819) with custom firmware.
I know that you can get the 14M & 20M in SMD, but I have not seen the 18M is SMD.
Maybe if you ask the powers that be at TechSupplies for a SMD version of the FRM010.
I also would like this.

The FRM010 is based upon the PIC16C620A chip.
According to the Microchip 2003 datasheet the chip is available in PDIP, SOIC and SSOP packages.
However, all Rev Ed literature that I have seen has the DIP package chip variant.
Think it would require Rev Ed staff to confirm if a SMD variant is in fact available.
I don't believe there is a SMD version available at present and don't know if there will be one in the future but will pass the request on. Being an older 16C chip, availability, cost, production tools to program such an SMD chip, and potential market size might not create a good buisness case, nor may 'porting it to a modern chip'.
That is a shame there's not SMD version available because looking at the serial LCD displays available from techsupplies they seem somewhat disproportional, the circuitboard(s) look overly big for their purpose.
This is the LCD screen I want to use as it looks almost cute and ideal for small projects, just a shame there's a $50 min order for international postage and they don't post to the UK (?!), I'll have to find somewhere else.

That postage for items out of the US is often the killer.
Have a look at www.futurlec.com.au. (there is also Futurlec.com which I believe is the US arm and does have a slightly different catalogue) They may have something as an alternative you can use. Although they have an Australian “shop front”, the Warehouse is in Thailand and postage is extremely good.
UK members may be able to put you onto other suppliers in that region.

would it be the firmware chip that's gone, or the lcd as well? Thanksinglewoodpete

Just about every semiconductor on the board, I'd guess!

Agree with IP.
Just put it in the bin and chalk that one up to experience.
Even the LCD itself is likely to be damaged and without question the driver will be shot. Not something which can be repaired.
