I've never pumped an S200, but I've shot one quite a bit:) Friend of mine had one and it was a really nice gun, definately going to be a cut above the Disco price point gun. With such a small air cylinder I would guess they would be real easy to pump full, and if you keep it as a 12fpe gun your shot count will be "ok"....smaller resivoir, less air, less shots. The S200 has been compared as the "R7 of PCP's", and I would have to agree, they are real sweet guns...and they make a 10 shot magazine option also if you end up wanting a repeater. There's also the old style 12fpe Air Arms S400C to consider for (I think) about the same price as the S200, a slightly bigger resivoir, more air, more shots, more pumping:) I think Pyramid has a few of these in stock, but haven't tried ordering one to find out. I think the S400/410 have Lothar Walther barrels on them, whereas the S200 has the CZ barrel. I owned a Tau-200 match rifle which is what the S200 is based on and I'll say one thing, THAT was an accurate gun. The LW barrel is also regarded as one of the best airgun barrels around, so either of these guns will probably shoot better than the shooter. Me personally having shot the S200 quite a bit, and having shot the S410 Classic quite a bit also (older brother of the 400C), it would be tough to pick between the two.....I have a love affair with the CZ guns though, so I may go with the S200 personally..., but that's just me:)
Good luck!
