picaxe 14m2 board

I think some one, read not me it would be a mess at my skill level, needs to make a picaxe 14m2 compact proto board like the one for the 08m but that has a voltage regulator circuit built in so we can use lipo's say able to handle 15v or so  and maybee 2 amps think of the possibilities

Any cnc folks

Hi All,

 Any of you familir with cnc milling, I would like to get into it on a small hobby scale, this is the lowest cost yet capable way I have found any opinions or observations. I will not be purchasing this till mid sommer so other ideas and option are welcome are welcome, I own a taig lathe and it is small but works for me, and I felt the quality was good for the money it is not cnc. I debated a non cnc mill but felt in for a penny in for a pound, budget is no more than $2600 or so complete.
