Can't believe I'm gonna say this, but....
Try out a Crate Blue Voodoo 60. I actually use one next to my Mesa Dual Rec (I run them both in stereo). These can be found very cheap (I bought the whole half stack off craigslist for $200). I am NOT a fan of Crate by any means, but this really is a good sounding amp on both clean and gain channels, and 60 watts is plenty loud, and keeps right up with my 100 watt Mesa. In fact, I actually like the clean channel better than the clean channel on the Dual Rec.
