My brother, nephew and I went 3rds in a hoist - you can see some pics in the thread linked below
Gettin old and fat(ter)
From memory we looked at Molnar but they were a little more pricey (especially for a home hoist).
Eventually went with Tufflift and the guy had a crew that installed locally for what seemed to be a reasonable fee so we opted for that too - all up just under 4k (from memory) He was very easy to deal with - everyone turned up on time and the installation was incident free. At the time he seemed to be selling quite a few and I wasn't able to find any negative feed back on the 'net (via google).
If you can stretch to a clear floor lift do so - not having the lines between the posts on the floor makes it much easier for any under car work. Particularly if you have to wheel anything heavy under the car (like a tranny or diff) when the little bump becomes a big obstacle - also one less thing to trip on when you're looking up.
Sometimes our hoist will stall when trying to lift from a point part way up - where we stop the hoist to remove the wheels - we just let it down a little then it goes fine again. My brother was able to explain why this happens but I didn't really take it in past '..it's no big deal, the ...'
I was keen on a four post lift because I imagined that most of the work would be drive-on / drive-off, (and I think it was cheaper) however as a former mechanic (having used both extensively) my brother would not consider a four post hoist on the basis of ease of access to the car and remaining workspace around the car (not that they don't have their place)
I have to say it's a great piece of kit to get and makes life a whole lot easier when working on a car.
Cobras are high maintenance and if its easy to get under there and have a look then you're more likely to do so - stitch in time and all that
Good luck with your choice and show us a pic or two when you're done
