I use a the big one... :) 18F4550 in DIL package form (easier to hand solder)
it is a bit big, but plenty of I/O .... so plenty of options / buttons... ;)

I'm sure it's a fun project, but you can get these for £23 delivered - http://www.ebay.co.uk/itm/3-Axis-CNC...ht_3091wt_1163

Tenson,
I wouldn't recommend one of them. It doesn't have a proper emergency stop button and I doubt it would fulfill any legal requirements in this country . I really would hate to try and hit that little foil button and rely on it in an emergency.

Ideally one should not rely on software at all for an emergency stop button. I guess it would be nice to have one in your hand, but surely having a couple of E'stop switches on/near the machine is sufficient. There may well be other reasons not to get it...

But then again something like the shuttle can be just for jogging and that doesn't have a stop button, software or physical anyway.

Easiest way is to grip a proper E-Stop button between the cheeks of your arse.
Anything goes wrong and believe me you will press it
