Hey, folks -
Just wanted to provide an update. After spending some time looking at the QuickJack specs and measuring my cars again, I decided to buy the BL-5000EXT. I've got two cars that really seem to need the 66" lift span.
The downside is that the EXT model is new and doesn't ship until mid-August. I'm hoping it will be in my garage in 3-4 weeks.
A couple of years ago I ran a dedicated 30A sub-panel to my garage. I chose to go with the 110V option for the QJ. I think what I'm going to do is to run 2 new 15A circuits off the panel -- 1 for the lift (and maybe compressor down the road) and 1 for a portable A/C unit I recently bought.
Damned if I won't be working in the garage almost like a human being soon!
