Searching for a (special?) tablet

I’m searching for a tablet (a drawing tablet, like a digitizer) with these features:

  • A4-size
  • Wintab compatible
  • The drawing tool (e.g. a special pen) musn’t touch the pad, it has to work when the pen floates above the pad
  • €1000 is the limit…

Since I googled for 2 days, without much success, I’d really like to have some help…

thanx in advance!
