I really must ask... How can guys fucking afford all that! XD
I'm working as a P. Eng (mechanical engineer), I'm not rich, but I'm not poor either... and it took everything I had to afford ONE head!!!
I guess that being in Canada and being screwed for everything I buy doesn't help. Since yes, not only is our dollar quite low, but everything we buy is 150% the price in USD (so yes, 150% of the price plus roughly another 130% for the exchange rate).
The used market isn't great. Only Marshall stuff, couple of Peaveys, some EVH. But good luck trying to find Diezel, H&K, Laney, etc
