I have built some test circuits using a 28x1, breadboard, and the Cosel VAA505 power supply and have not found any issues with it - Downloads ran fine, the Picaxe performed as expected for a 45 minute test...

My concern is the spec that indicates it is a 5V >>1.0 amp<< supply - I read somewhere that Picaxe chips should only get 200mA max... Is it just blind luck that my 28x1 didn't fry?
If I need to be concerned, some advice on how to knock the input current down would be most appreciated... Choke? Resistor? I went with the VAA505 because it was small, compact, and simple. Hopefully the required adjustment for the current will be equally simple.
