For whatever reason it seems like these cabs aren't discussed very often.
I have the Marcus version that I bought as a b-stock from Musician's Friend. I like it.
Weighs 55 lbs so I can lift it on my own, fits in the back of my Jeep, and sounds good with the variety of amps I've used with it. The only problems I've had so far have been minor - one of the castors became slightly bent and one of the corner protectors cracked. I haven't babied it, but I haven't subjected it to any unnecessary abuse other than the typical load in. In any case, it works for me. Plenty loud, rated up to 800 watts power handling. One thing I like about the MM version is that it's 4 ohm. I think you can get the regular ported version in 4 ohm too.
