Hi Jay,
I'm sort of in the same boat as you, I've been setting up a new room but it's upstairs instead of down. Carrying the stuff from my car to the house was becoming a pain-literally, because as luck would have it I kept pulling my back just before a new piece of gear arrived. I bought a little wooden dolly from Harbor Freight for like $20 bucks and it made life so much easier, now I just roll that baby right to my door step and then I try and grab a neighbor to help push the box up the stairs, this has worked out great so far.
I'm currently trying out the No 8 and though I only have about 48 hours total on it I have to say it is shockingly good.
