I use a Yiynova MSP19U (though I haven't made a map with it yet), which is basically a Cintiq (i.e. a graphic tablet/screen hybrid) without the price tag. I saw this review ages ago, and ended up buying one. It's awesome. I've used a Cintiq in the past, and actually marginally prefer this, since it's more sensitive at lower pressure levels, which to me feels more natural.
