I have a Markbass stack that's easy to throw in my car and go. It's ok for messing around and small rooms/house parties, but I have been happy to have that SVT Classic and the 610's when I needed them. Even with the VLE knob on my MB combo, it's not the same as a tube setup. It's not hard to move gear if you use the right support equipment like straps and a dolly with tires instead of little hard plastic wheels even stairs are not hard to maneuver with support equipment. Once I had to move gear up a long series of steps (like 3 stories) 180 turns every 10 steps (like 6 turns) and across a 25 or 30 ft cat walk to get on to a Aircraft Carrier for a 12 hour friends and family cruise. Having the gear in touring cases and straped to a dolly made all the difference (less trips up and down and 10X easier). I watched these other guys do the same thing with their gear piece by piece muscling all of it up the steps with their "rock star" garb on, I thought they were going to cry it was funny. So I would keep your gear and invest in support equipment.
