Well I bought a new one yesterday from Gene at Ultrasound based purely on the fact that I'm a Tweedaholic and Tony Bruno's stellar reputation, figured it was a no brainer!
If you do some searching here on TGP you'll find a few reviews. IIRC they are mostly pretty good. The 18 watt seems to be more along the typical 5E3 lines - the reviews of the 35 and 45 watt models have been great.
