I'll be using these boards as part of my research, but they seem a little overpowered for modding projects...although I'm sure the guys here can think of something to do with all that power and bluetooth connectivity

PS: I've only been exposed to our Comp. Sci Arduino boards, we have about 3 or so in the dept. and they're high-end all-singing all-dancing models, if there's cheaper ones out there I don't know about them...
