I have a Multirig PRO for sale. It is the $485 package with the supporting rod and shoulder rod. I bought it directly from them for the same price 1.5 year ago.
It is in great working condition. It functions just as well as when it was brand new. It was some small scratches and tiny paint loss from normal use. I shot a short documentary with it on a Sony EX1 last year. It worked very well.
I'm selling this because I just bought a GH1 package, and I bought 15mm rod support for it. Now I have no use for the multirig.
When I first got the multirig I wasn't very happy with the design of the locking screws on the handle joints. They weren't as tight as I wanted. I exchanged emails with DVTec and expressed my concerns, and they was nice enough to Fedex me a new pair of locking screws with oversized knobs to accommodate my needs. I think you don't get these special oversized screws with their regular package. Now I have both the regular stock screws and their special oversized screws. So you have a choice in case if you want to go back to the original.
I can sell this rig for $390 + $20 shipping. I hope that will work for you.
