Look on the used market, you should be able to grab a Mesa 4x12 for closer to $500. I bought my OS Recto4x12 cab for $250!!!!!
Everyone says traditional but I'm telling ya, my Mark IV sounds AWESOME on this OS 4x12 that I bought. I had an older Marshall 4x12 from the 1980's loaded with old 65 watters. And the IV sounds a LOT better on the Mesa OS4x12 than that Marshall cab. Mesa and V30 just work. MC90's and EVM 12L's aren't bad either.
Greenbacks, H30's, 65's.....better for Marshall style amps IMHO.
