From the variety of discussions I've seen, most would say go the Wacom route.

I've got an Intuos4 (wacom) and I've never regretted the purchase. Some of the most amazing works I've seen on this site (and deviantart too) are from the Bamboo series, so those are nothing to sneeze at

I couldn't say much about the other pad you mention though it seems to have some ok reviews from amazon.
