Thanks again for the replies. Ioan1k mentioned KOMODO EDIT (version 5.2 just released), which I'm taking a look at now. It is really nice and, despite all its capabilities, very user-friendly and...what's that word?...oh, yes...FREE.

Never heard of the SUBLIME TEXT EDITOR (mentioned by Sirupsen), but when I started reading about it, the reviews were pretty fantastic. However, the website will not come up this evening (www.sublimetext.com) for some reason.
