Yes, prog and 80s synth go together because prog was so huge in the 80s. Oh wait, it wasn't. Dude, you're just making yourself look more ignorant. Prog is most identified with B-3s (which weren't even MADE any more in the 80s), Moog synths, Mellotrons (a 60s invention MOST famous for a freakin Beatles song), Rhodes (a 50s invention), etc... NOT 80s synths like the DX7, PPG, Fairlight, D-50 (unless you count JMJ), M1, etc... Synths in general are HUGE right now, and a damn CS-80 which probably cost $5k in 1978 costs MORE than that now, and it weighs 150 pounds and only has 8 voices (modern keyboards have up to about 128 while weighing a 10th of that). But it sounds freakin amazing so people still lust after them (and actually yamaha just put out a sort of reissue/interpretation of it). Moog is probably selling more units now than they did in the 70s. You have NO idea what you are talking about. At all. Not to mention, keyboards in general can LITERALLY sound like anything from dubstep to motown. The limiting factor is not "coolness" at all, it's the fact that playing keys (well) is a lot of damn work. I know, because I do (and have been SINCE the 80s). So a lot of people don't put in the effort to become great at it.
Bulldog, keys are difficult to find, but not impossible. As far as gear, you can do a lot with free plug ins these days if you're on a tight budget. The Mel9 is cool, but it's not really up to the task of "replacing" a keyboard player and I'd rather just hear a guitarist making guitar sounds. I don't want to see someone playing Watcher of the Skies with a Mel9, that just wouldn't be right at all. That kind of stuff should be used sparingly. Even an average keyboard player with average gear would be better in most cases.

). Like you, dear OP, we were in it for the love of the music and just for the fun of playing together. The drummer and I still get together and jam/write almost every weekend since he finished school, and are hoping to start recording our own new material as a "studio" 2 piece band, with no intention of playing out, so I'm still writing "prog" music today, thanks to the relationships I made during that time period. Again, we write more math rock based material than symphonic stuff, mainly because it's just the drummer and I, so we work on rhythmic/riff based music. You can definitely do it, although like others have said, the music scene at large is unlikely to support a prog band in the 70's sense, ala Yes or Genesis. At-home recording has become a very viable option for musicians, and that's the avenue that my drummer and I are taking in order to get our experimental instrumental music out there.
