Some of the older big Thiels can be had for amazingly cheap. I really have never liked them, though. They just don't sound good to my ear.
However, I did buy some Harbeth SHL5's. They were a bit out of my initial budget, especially considering the overpriced stands they needed, but I like them very much. Not only do they look the part, but they sound great from everywhere in the room. I am powering them with an Adcom power amp I picked up off of eBay for about $120, and the sound is pretty spectacular. I had been planning to build super fancy power amps for them, but I am not sure I can see the point now.
