21" LCD's are damn expensive.
There are a few on NCIX but they are also over 2 grand.

More at Canada Computers, they are also 2000+
BCom also has some but are indeed 2000+ once again.
LCD's get really expensive once you get 17" and higher it seems. IMHO I'd take a 17" over a 21" considering every LCD that big has not so good response times. If you plan on playing games on an LCD I would not recommend anything high then 16ms response time.
One monitor I have my eye on is the NEC 1760NX 17" going for $735 at BCom, although they did have a sale a couple weekends ago and it was going for $688.
