I have a Mig100 that I gave $50 for and then put another $450 in to fix all the fixxing the previous owner did sad silicone repairs haha, plus all of the plastic parts that were in it had to go and all of the cheap wiring was replaced. Now its a very reliable, OMG loud and heavy with no extra noise amp the does dirt sounds awesome and you can't get a good clean sound out of it to save your life. It has 6L6's in it which I figure is part of it. I bought a used Genz Benz El Diablo and have the best of both worlds. If that Mig is anything like mine and you want use it for more than just distorted sounds I'd pass as far as low end sound I ran a MXR 10 band Eq in front of mine and I could put more bass to my speakers than they could handle. For what it's worth I do still have my Mig100 and it will get used again I'm sure, but for now it set's there with all of the tubes pulled out of it looking dejected.
