I would imagine you could find a nice Disston for $20 or so that's worth the time to recondition and sharpen. I have six of them, 3 rip, 3 crosscut. If you do choose to go that route, there's plenty of info out there on how to properly sharpen them.
If you really, and I mean REALLY love handsaws, check out these works of art @ www.eccentrictoolworks.com. I covet one of these badly, but can't pull the trigger just yet.....Yeah, like a few others, I have a saw problem and it's not under control.
