Sovtek MIG owners

[mlove3]

interested in Sovtek Migs or as a mod platform, need a louder amp for a regular gig at a big room. can anyone tell me about them? anybody mod one?
what are it's dimensions and weight?
are they as insanely loud as they say? How much clean headroom, what setting does it start to break up?
found a midget 50h locally on c-list for $350.

thanks and have a great holiday!
