Just tried out a 100 and 200 combo at the local GC. They have a used 200 for about 250 bucks (might have to grab that, but it looks a little thrashed…). The 100 is silly light! But, the 200 is extremely light too for an amp that loud. You could still walk into a gig with it in one hand. They both sounded really good, and the 100 would suffice for 90% of what I do, but I think I'll go with the 200 just for that extra bit of headroom and low end girth. I'm a 15" guy from way back, and the 200 sounds "right" to me. I could also see adding another 15" for a tidy little 2x15 stack (I LOVE 2x15 rigs for bigger gigs). I also tried out the new GK MB112. It was nice too, but I thought the Rumbles sounded better, and more "classic". The MB112 reminded me more of my (long gone) Mini CMD121P, while the Rumbles reminded me more of my B100R.
