Looking for a lift!!!

I have a 4 post and lagged it to the floor. The concrete PSI requirement for the 2 post that I looked at scared me off. My car is pretty complete, so I only use it for brakes, oil changes, storage etc. If was going to be pulling motors all the time, then the 2 post offers more flexibilty. PS, I bought my lift from the Lift Superstore and the product is good, the customer service sucks. I ended up taking them to the BBB to get the rest of what was promised to me.
