Best Pentax K mount to Micro Four Thirds adapter?

Hi all, just hate the thought of letting all my Pentax K lenses going to waste. I'd love to use them on my Panasonic G3.  However after doing some research on adapters the prices and quality seems to be all over the map. can anyone let me know of some of your personal preferences or experience with any of these?  Looked at the DSLRKIT, FOTGA PK, ZYKKOR, AST brand, and the Voiigtlander adapters. The Voightlander I'm sure is the top choice (but it is very pricey, I'd like to find something a little less costly but still good quality.

Any help?
