Don't know about fitting under your bike, but I've had my J&S jack for 6 or 7 years now and it works great with no problems what-so-ever. It fits under my 02 Road King if that's any help.
Also if you are gonna bit the bullet and get either a J & S or pitbull, the only thing that sets them apart is that the pitbull can spin 360 with the bike on it and I didnt know that until I bought my J & S. I would have bought the pitbull if I would have known......
My Pitbull air operated lift with swivel table is great. No pumping with your foot forever and swivel table let's you easily turn bike for best lighting as you work around bike.
I got a lift off Craigslist. I see them there regularly for $40 to $300. I do not know the brands. I got a lift for $75 bucks that is like new. It holds my RKC very stable. Easy to pump up with my foot.
Got the OTC 1545 lift for my 07 Ultra Classic for $149 on Amazon.com.
It is a low profile heavy duty jack that will slide right under my frame. It weight around 80 lbs.
How much for that lift, where did you get it and can it be operated from a small (120 PSI) compressor?
You can check the pitbull website for the current prices.
I'm using a standard 30 gal, 5 hp 110V home type air compressor.
The biggest reason I went with pitbull instead of J&S was because of the higher lift on the pitbull. If you don't need that, you could probably save a little money with the J&S.
