Everything they say about these combos is true - check out the Mesa Walkbout megathread on the Amps Forum. Absolute tone monster, and the amount of thump via that downward-firing passive radiator is a gift from such a small, 50-pound package. 300 watts into the 4-ohm cabinet, and many folks report extensive use with 8-ohm or 4-ohm extension cabinets. Killer tube preamp and a MOSFET power section makes for some great sound. And it's not just old-school - keeping the gain low and the master high gets some great contemporary tone.
This particular sample has custom tan vinyl, with a straw/bamboo-colored speaker grill and leather corners - imagine some blues band kicking it out in the Mississippi Delta, circa 1958, and you get the vibe. For pictures, go to:

One of the 4 screws securing the handle could also use some TLC, but operationally, there are no problems whatsoever with this unit.
Regrettably, I have two flights of stairs from street to home, so I've gone to an even lighter, modular rig.
Balancing life experience with the custom cosmetics, $800 plus shipping seems about right.
Looking for cash only - am pretty set on my current rig and instruments.
