Display suggestion

I have a project in mind that I think would be well-suited to the PICAXE. I want to build a hand-held timer for my race club (as in foot-races - 5K, 10K, Marathon, etc.).

For a display, I want to maintain several (6ish?) lines that contain a 3 digit position, a 1-digit hours count, a 2-digit minutes count, and a 2-digit seconds count. eg.

001 0:58:10
002 0:58:30
003 1:01:02
etc.

However, all of the alphanumeric LED display I've been able to find have the wrong aspect ratio. They tend to be short and wide.

Does anyone have any pointers to where I might find a tall and skinny LED display (or some other display technology like LED or TFT) which is easy to interface with a PICAXE?

Digole OLED display.

This could be just what you're looking for : http://www.ebay.co.uk/itm/2pcs1-3-Serial-UART-I2C-SPI-128x64-OLED-LED-Display-Module-White-for-Arduino-/370766734005?pt=LH_DefaultDomain_0&hash=item56536b62b5
It has several font sizes and the ability to define the text origin at any corner so you could have the screen vertically and have several rows of characters.
Serial, I2C or SPI interface. It has a micro on-board and uses it's own command set which takes a bit of decyphering, but all works pretty well. Manual is here : http://www.digole.com//images/file/Tech_Data/Digole_Serial_Display_Adapter-Manual.pdf . Delivery took a week and a bit from China to UK.

I bought a pair of these a few weeks ago and was putting together a Picaxe driven demo for it but then the better weather arrived and the garden called so haven't quite finished. I'll try and get something up by the end of the weekend. (I'm quite proud of my bouncy ball animation ;¬)
