The Digidesign products are very good interfaces, however, there are some other products out there that are definitely worth a look.
I would also check into these:
Mark of the Unicorn 896 HD
Personally, I own the Presonus Firepod, and I have been very happy with its performance. It is nice to have 8 good sounding mic preamps on an interface, and it was easier to install than anything I have ever installed on a computer before!
Also, if you get the Firepod from Musician's Friend, you get it for half the price of a 002r, and it comes with a free cheap AT condenser that you can use or sell for $80 or so, so then you have an 8 input firewire interface with Cubase and 8 mic preamps for $520. Now its not an HD rig or Apogee, but thats quite a deal.
