Maybe it was this one (called the "El Greco" .. if so, I need to get to walmart:

As for what I do, I have a few setups (some in use, some waiitng for a wall to attach it to).
First one is a ghetto version of the El Greco, two pulleys (single) attached to the ceiling via hooks, then another (double) attached to the right where both ropes go thru. Pull down, on the rope, lifts the bike via some hooks. I hate it, but it works, mainly because I have a 12' ceiling in my garage. Hardware cost me around $10 (3 pulleys, 2 hooks, 3 eye bolts and rope) ... but my pulleys suck, so it's overall crappy to get the bike up there. Advantage is that it picks up any size / shape / weight bike.
Second is a Swagman Fold it:
http://shopping.sympatico.msn.ca/Specs/shp/?itemId=10386155 . It claims to be able to hold 20kg (44lbs to the layperson) but I don't know. I have hung my 31-ish lb Enduro from it (with adapter bar, probably another 2 lbs) and it flexed enough that i'd say that's its max. My roadbike, however (24-ish lbs) doesn't move it. Pretty cheap ($12 I believe I paid)
Third is my basement mount, this thing is AWESOME ... but it didn't come free at all.
http://www.saris.com/p-171-bike-bunk.aspx .. it's Saris, and it holds two bikes without needing to be bolted to anything ( just lean it against a wall ). Lots of adjustment, but the cost is there (paid around $90 I think) ... very nice and compact.
BTW: whoever has that sexy Surly, is that a Pugsley by any chance? A guy brought that to a race to show off riding around the sites (not racing) and let me take it for a spin; awesome bike.
