Cheapest scanner compatible with Mountain Lion?

[Buck]

Ever since I got my iPhone 4S, I've stopped scanning. Just take a picture of whatever document!

I keep XP on VMWare just to run my scanner, now that the Mac no longer honors the driver. One day I'll try if the scanner can work under Crossover, which doesn't need the Windows OS overhead.

Also, what Buck said: My point and shoot now records a lot of documents I used to scan. It's faster and the quality is OK enough for documentation.
