I wouldn't recommend New York Toy Collections for STPs. They don't make them as STPs and they are silicone which is hard to work with. Something like a Mr Limpy STP (ready made ones are available thru FTM Essentials or other stores) is a good idea or for uncut Stylish Flesh which a lot of guys seem to like.
Tranzwear does have smallish STPs and packers.
Good luck, and sorry if this all overloads you.

Yes, $2000 is bizarre. Not all guys really even LIKE STPs/packers. And it's on the high end of prosthetics. I think Reel Magik is in the $1000 or less, but even then, it's pricey.
