Funny think about the TB-303. I found one in a pawn shop while I was in college in College Station. They had a TR-606/TB-303 for 60 dollars. I was just beginning to get into my gear head phase and remember reading on one of the early internet music sites what an important piece of gear it was. Thinking its too good to be true, I took an extra 386 PC I had laying around and offered it in trade(I was broke and didnt have 60 bucks). They accepted, and I took home these 2 boxes. This was around 1997 I believe. Wish I'd have kept them, but I ended up profiting pretty nicely from them.
The SE-02 is all right but let's see what happens when Behringer introduces its Moog clone for $300! http://www.factmag.com/2017/06/28/behringer-d-synth-pre-orde...
The 303 sound was first emulated in 1996 and later by plenty of soft synths. By the time Roland re released it was mostly a novelty to have an original machine.
It reminds me of Nintendo's failure to capitalize on ROMs and the persistent popularity of both NES and SNES for two decades ...and when they finally did they still managed to mess it up.
