gabesax, if your budget is $1000, you're not far off from some of the ROC-made makes that are widely discussed on this board. I would look into the Barone and see if it's near that price (I name that brand only because you can research it here, and I have seen its pricing at $1400 or so, though that may be out of date, I have no idea). Most of the better ROC makes are very comparable to modern Selmer, and some of them play better than modern Selmer (especially if you prefer a slightly more flexible pitch center than is generally characteristic of the Series III) -- and definitely many of them will crush a Yamaha 62 (for e.g.) on character and tonal complexity. I also saw a make hyped on this board, recently, with a model at $1400 or so, whose keywork appeared to be very similar to P. Mauriat (that doesn't mean that they'll play like PMs, it's only a clue that the *general* quality may be similar).
It's very unlikely you'll find anything (unless an ROC used) that is truly like a modern or vintage Selmer in the right condition at $1000. Vintage American doesn't have a bigger fan than me, but worthwhile tenor models in proper condition will not be in the $1000 range unless you find one where the seller doesn't know what s/he has, and those with keywork that approaches modern-keyboard Selmer for overall slickness will be quite a bit more.
