I've actually been talking with them about a 2 post asym 10k. Was ready to pull the trigger, but I found my slab is a tad thin. So now I have to cut it and build in some 36x36x12" footings, so I delayed the whole thing till I can work that out. If this comes in "right", that would motivate me to get it done, and I would be in for a 2 post.
I hope their 4-post lifts are built better than the mid-rise MD-6XP that I purchased from them last year. Very poor, at least in my eyes, attention to detail in a crucial, load bearing area. I have asked BP about this, and they say it is fine.
That being said, I believe some or all of the 4 post lifts are ANSI/UL201, which should be better. Depending on price and if they seem to be quality units, I may be in as well.
I am waiting on the pricing right now but will get everything posted when I get an email back. I know they were discussing pricing on 5-10 units to start. It looks like we might be able to at least do that and then some.
