For a 21inch CRT which will do 1600x1200.
You'll never
ever get a 20inch LCD for under £300 (assuming you need a gaming one with a decent response time).
There are a few nice 19inch ones here, some of which are ~£220 - 250 - their native res is 1280x1024. Moving up to a 20 inch will cost you at least half as much again...
