Edmika EOS lens mount

I just bought a 55mm Canon lens w/ an Edmika mount for converting FD lenses to EOS. Has anybody else tried one? I like the fact that the FD mount is replaced as opposed to putting on an adapter ring. From what I can see it looks pretty solid so I'm curious to give it a try and report back if anybody is interested.
I've been having trouble finding an affordable manual iris lens in the 50mm range. I know old Nikons are a good option but I was hoping to find something without the reversed focus direction. The one negative that I've read is that some of these adapted lenses may block the mirror if you use them on certain DSLRs, so they may not all work if you also do still photography.
Here's an eBay search for the mounts: http://www.ebay.com/sch/i.html?_nkw=edmika
