My local camera shop has been selling these "Pana-View" scanners for a while;
Pana-Vue Pana-Scan APA121 Portable Stand-Alone Slide APA121 B&H
There are many similar products, some of these can take 120, though this particular one cannot.
They showed me a couple of 3x5 sample prints that looked reasonably good. They tell me the customers using them have been pleased.
For web and computer display, or snapshot size prints, it's probably just fine. For large prints, etc. probably not so good, but the price is well in your ballpark.
A flatbed like some of the Epsons, Canons, and even HP will work as well, or perhaps better, for modest print sizes, and let you scan other stuff too.
As stated, you get what you pay for. I like my Coolscan, but even though I got it for a bargain price it was well above your target $'s.
