I've been doing a bunch of PHP lately, and found HTML-Kit.
Free, simple, quick. Hit up Barnes & Knowbles and grab HTML in 5 Easy Steps. It's only $10 & they have a good selection of them. Barnes & Knowbles is actually the publisher of them. Purple covers, can't miss them. I picked up PHP in 5 Easy Steps, and it's a helluva lot better reference then the $70 PHP & MySQL book I got.
ps: notepad rocks.
