The Palmer is a realy cool piece of hardware, makes a big difference to overall tone. Actually, I picked up a brand new model from a German website for around €350. They are so much cheaper in Germany (that's where they are made), here's a link:

I emailed them saying that I couldnt speak German and a guy came back to me with a link for orders in English, very helpful.
Anyway, I would definitely go through the Boogie poweramp, that has some absolutely monster power, 2 x 90 watt all-tube channels! I can crank that baby up to ridiculous levels then run it through the Palmer. The sound is absolutely crazy! Without the Palmer I would never get this tone as it would be impossible to crank the Mesa gear up, its simply too loud. Check out the above link if you're thinking of getting one, excellent product.
Anyway, that setup is what I was thinking of alright - thanks for the reply!
