Dargo,
I have a 2 post lift made in the USA by Challenger Lifts located at 200 Cabel St. in Louisville, Ky (challengerlifts.com) Mine is rated for 9000#, only needs 12' height to bottom of rafters, will lift 6' high. They sell 2 and 4 post lifts up to 60,000#. I bought mine in Oct. 99 for under 3200 installed. I wired it myself. Make sure the lift you by is tested and certified by the Automotive Lift Institute for ANSI/UL standard 73. I bought mine because of Murphy's law. Seemed everytime I had to work on a vehicle it was either raining or snowing. I use mine on a weekly basis and have not had any problem since installed. I don't know the quality of Chinese brands or whether they have been tested or certified. Rotary lift is another company but they were more expensive in my area. Any other questions just ask.
George
