Hi there! I bought a SG 61 reissue about 1 year ago now, and after trying dozens of amps in all kinds of music stores from Las Vegas to San Francisco I learned a valueable lesson: don't let a brand name fool you! There are so many good amps out there which will give you loads more power and tweaks for less money than say Marshall, Mesa, Vox etc etc. Don't get me wrong, these are brilliant amps but they are expensive. If you have a limited budget do some research. I ended up with the Egnater Renegade 112 Combo 65w and It's awesome!
Compare the specs vs price for these two for instance:
