I have used the Sovtek, JJ Teslas and Valve Arts in my Copland CTA-402 integrated. My favorites are the Valve Arts. Abstract7 mentions the Harmonix. Here is a link to a dutch auction for a MQ at $49.99. These retail at $71.00 on Harmonix web page.

There are a bunch of EL34s for auction on singles, MPs and MQs on Ebay all the time. Sometimes they are a good deal, sometime they are overbid.
