I've got a pretty cheap scissor lift from Amazon, chinese-made by Baishite. It's rated to 1100 lbs and has a footprint of about 18 inches x 11 inches. Super small but works well enough for my sportster. I paid $58.99 USD for it, it won't be a heartbreak should it start failing on me.
Space is pretty limited in my garage/shed and I'm not doing anything crazy so this has worked out well for me so far.
