My suggestion is to look for the Olympus Variomagni and make sure its the OM version and not the newer one for their 4/3 system. These are almost as good as the Pentax one and a lot better than the Seagul, etc. ones you can find on Ebay.
The old OM version can be found cheap. I just this last week picked up one new in the box for $75 including shipping.
I'm not the OP, but many thanks to the numerous recommendations on various threads for the Olympus Variomagni. Mine arrived today from an Ebay purchase for less than the amount mentioned above. It is better built than any third party finder I've tried, and optically first rate. It fits all of my 6 pentax K-mount bodies , digital and film, as though it had been made for them.
This is one of those times when this forum has been invaluable. My travel tripods and manual lenses are now far more useful.
