RH200SC can anybody tell me about this amp before I buy it.

Im a newby here and I was just wondering if any of you vets on this forum could tell me about the RH200SC head I stopped by a local pawn shop and they had a RH200SC head in there going for $250 w/ footswitch. I didnt get a chance to try it out b/c I was in a hurry, I'm going go back tomm and test drive it, but I want to know all about this amp and what to expect from it if possible(Pro's and con's) I'm looking to for a sweet metal tone, will this amp do the trick, or should I just buy a RH150 G3 Plus? If you guys could help me out that would be cool!
