I'm sick of trying to use my mouse to do Photoshop drawing. I know the standard is to to use a digitizer (a.k.a., pen tablet), but I don't want to sink hundreds of dollars into one when I really just need something more ergonomic and responsive than a mouse for some details.
Are there any obvious entry-level digitizers, or is it not worth it until I'm ready to pay up for the pro-grade digitizers?
