I use a whole bike lift like this one:
Harbor Freight Tools - Quality Tools at the Lowest Prices and have several years experience with it.
As Hobbit says, Sporty's tend to scrape going up the ramp, which can be remedied with the correct placement of a 1 x 4.
In addition to the ramp, I also use a thin scissor lift on the ramp to support bikes for rear tire removal, shock replacement (needed on nearly every brand) and the like.
All in all, things really did not get expensive until I built the heated garage...
I live in Wisconsin and still have a few more months of polishing to go...
