I have a Ruger Redhawk 4" in .45 Colt that I'm pretty fond of. I see one for $750 on GB right now, so you should be able to find one somewhere near the ballpark you're looking it. Here's a decent writeup on it and its .44 Mag brother.

Note it comes with Hogue rubber grip, but replacement grips are readily available and not particularly expensive depending on what you want. I had wood on mine for a while for looks, but ended up swapping back to the rubber for comfort when shooting.
