Help--with my crushed vertabrae from a motocross crash, bad knees and hip from old age, rolling around on my shop floor to work on my bike has lost its allure.  Does anyone have a line on a lift like the shops have that doesn't break the ole piggy bank???

I have one of these - 99$ - and aprox the same crushed body as you It's a very great help, and it can be rather high so you can sit comfortably .

I have the Harbor freight lift in my shop and it is a great lift for the money. It was only #200 when I got it. Nice drop out panel in the back end makes tire changing easy. I put a PU or trailer bed front wheel chock  on the front end to replace the cheesy front wheel stop. Still use tie downs but is very secure that way. I also have a Handy version, the one many shops use and the front wheel (or rear) clamp the tire/wheel tight enough I don't feel the need to use tie down. It was $600 when I got it and I did order the ATV extenders at the same time so it was a chunk of $. Have used it lots and even was able to lift my side before it was re-rigged and a Kawasaki MULE 1000. It is air operated vs the hydraulics of the Harbor Freight version. There are also plans available from AFAB (email plans @afabonline.com Ph 4805755677 to build you won (or have it built for you) and BigMaxx Company in OH makes a rail style rather than platform. Happy shopping and deciding, MAx

You can try http://www.nightrider.com/biketech/bikelift.htm . I know a few people who have done this. I'm planning on building one for mine within a few weeks, when the snow lets up a bit. The best part, it's under $20. I'd call that a stocking stuffer for yourself.  

Thats still pretty much on the ground. I have milk crate Ive padded & stuck casters on. I can roll around the bike, sitting.You can buy those seats that are much more comfy.
I also use old blankets to lay on, to keep the concrete from causing me too much discomfort.Even cardboard makes a decent Po'Boy Creeper.
