Hummm, the seller of those ASL WAVE 8's is asking nearly double what they sold for brand new a few years ago. Admittedly they were a bargain at $99/ea. (no cage), $119/ea. (w/tube cage), but $400 seems a bit obscene to me.
Another nice choice would be a Sophia Baby. I saw one here recently for $295. There is a small tube amp kit called SPUD being sold on the Hawthorne Audio site for $285. You would need to build it, but it looks like an easy build.
You might want to consider the simplicity of something like the Trends 10.1. It cost $150 brand new and it has gotten excellent reviews. Another choice might be the Super-T amp from Sonic Impact, $139 brand new and it has also gotten favorable reviews. Both the Trends and SI Super-T would produce basically zero noticable heat.
Enjoy,
