My PiquotWare 6 cup teapot doesn't drip, and looks lovely!
They've been making them to the same (or similar) pattern for the last 70 or 80 years. You can still buy them new (not cheap though - 5 piece teaset = over £400!) or you can find them in every antiques centre.
I got mine on eBay, 5-piece teaset new and unused for about £40. You will find quite a lot under the heading "unwanted wedding present"!
Anyway - beautifully made and non-drip.
