Functionally, there is not much reason for the layman to worry much about whether FASST or DSM2 is better although the hardcore geeks will argue to the death about it. They both work, and that's th important part. Decide which transmitter fits you hands better, has the mixes and memory you need, and you'll have a pretty good choice on your hands either way. One thing to consider--at the moment, Futaba only has the one receiver available(medium size and $89), while Spektrum has receivers for everything from giant scale(dual Rx,mini size $79) to park flyers(all the way down to sub micro and under $50). It probably won't matter to you unless you fly really small stuff or need to buy a lot of receivers...
