I like the two post mainly for just normal maintenance.If you have to drop out a rear or a tranny the four post is not nearly as handy. Most two posts are a legitimate 7,000 lb or better rating and can be used for long term storage as long as your cement is thick enough for the proper anchors. My 65 literally sat up there for several months while I was trying to get other things done. The cheaper Chinese hoists ($1800 delivered to your door) seem to work quite well,but they are often a 7,000 lb hoist marketed at 10,000 lb. We put one in my dads garage and it works great for occasional use. If you are literally using this every week I would go with Rotary,bend pack,challenger,aamco,etc....marketed in the U.S.
