Dunno if you've bought it yet, but Wacom is generally the way to go, however i could not find the pressure levels on the page you posted, Generally around 1000~ is very good, though I've seen as high has 1900~ (for like $2kish CAN O_O).
What you've picked out there looks pretty good overall. Also a good price.
My advice however is try to get in touch with some digital artists in different places on the web, and ask which features are essential, which aren't, and which are just extra lines on the feature list. That way you're sure to get the best for your money.
Good Luck with buying it
