I have the Kapex and UG. The UG stand is great. Awesome way to roll into a job, set up quick and get going. My only issue with the wings is that they aren't wide enough. for x8 or narrower its not an issue, for x10, x12 its a PIA. If you cut a lot of wider stock, clamp an extra width support onto each wing.
I've thought about the Kapex MFT but just don't need it. An original idea was to buy the Kapex MFT and then make my own wings. Reality though is that I'm too busy working to make my own Acc.
The set up is pricey but once you roll it and out of a job a few times and see others guys stare in envy it doesn't matter.
