You'd have to specify, exactly, what titles you are looking for and what you think is reasonable. I personally happen to enjoy the PC-10. However, I will warn you up front, there are PLENTY of folks who have no love for the PC-10, on this forum. Keep that in mind. You may come across some good deals here, but they are sporadic, at best.
That being said, you may want to check out the PAR Playchoice website or the Playchoice 10 forums site.
