A couple/bunch of years ago, I hooked a friend up with a lathe that was being sold by the outfit My Brother In Law worked for, that would have suited your needs well.
Given your size range, and area, I would expect that while they are not thick on the ground, there should be a few well used examples available and inexpensive too, as you are getting well past the usual "hobby" size machine, even for the guys that can handle some reasonably. I'll ask my bud what happened to a friend's 16 inch (rated, not actual!) Monarch. It may still be in the area of Edmonton.
