Depends what you want to do with the TV. If you're planning on running upscaled DVD or Sky HD, then you're not going to be able to do that with your CRT. And I reckon the latest 32in LCDs have got pretty special now, so you could upgrade with confidence you really are upgrading and not sidegrading.
And yes, before Andy C or Clare mentions it - 32in Supertest in October WHFSV, on sale next Thursday, the 23rd.
I thank you...
