Good combo amp under 200 dollars?

alright so I'm in desperate need of a good combo amp that's under 200 dollars :P right now I have a Randall KH-15, it's a 15 watt practice amp that's been great for practicing leads and solos and stuff like that, but it sounds like **** when i play rhythm. I need something that has a good amount of crunch for rhythm guitar. I play metal. Stuff like Metallica, Megadeth, Exodus, Testament, Pantera, Slayer, Black Sabbath, Iron Maiden, Led Zeppelin, well yeah I think you get it lol.
