I'm about to to buy one of these radios. I know Spektrum has been around for a good while and they have awesome customer service. The Tactic 650 seems to be a solid Tx for the price with what appears to be some extra functions that the DX6i doesn't have (except for model match on DX6i). Hobbico backs them up and has been in R/C for a long time as well. I can't decide which way to go. I've read reviews and spoken to owners of both radios. Just can't make up my mind?
