Anyone Seen or used this?

eBay: PENTAX 645 MOUNT ADAPTER K for 645 LENS/38455/REFURB (item 280109311800 end time May-03-07 17:01:10 PDT)

Anybody had any experiences with this adapter? Will you get infinity focus and focus confirmation?

The adapter allows the use of PK645 lenses on any K mount Pentax. However, there is no auto stop down, so you will have to use in manual mode only and stop the lens down manually. Focus confirmation may be possible at the larger apertures but may not work once you stop down several stops. Naturally the trick is to focus and compose wo and then stop down for the final exposure.
All this is slow and tedious unless you are working on a tripod or in a studio.

If you want to go that way Tim, have a look at, someone's been trying to sell some 645 lenses on there for a while.
