The ones with contacts are extremeeeeely rare. If you want contacts it's best to buy cheap tele converters and gut them.

Try this in an Ebay search box: Pentax KK-P25 Copper Macro Extension Tubes Auto Focus Close-up

The price seems right if all you want is to experiment.

(I have no connection to the seller or this item and can not vouch for its performance - or lack thereof.)

Is a achromatic close-up lens would be an alternative? Like this one

Kenko made a set and yes they are rare. The price they sell for reflects that. I tried for a long time to get a set only to be outbid every time. Finally I gave up a few years ago. The whole set normally would go for well over $200 which was more than I was willing to pay.

Here is just a single one right now with 3 days left.

The Kooka brand extension tubes have been discussed/reviewed in previous threads on PentaxForums. Search "kooka". The consensus is the QC on these tubes was terrible and the electrical and mechanical connections seldom worked. When they work they work great but the few people that purchased them seldom got working sets. And even the working sets would be finicky. SRB Photographic in the UK stopped carrying them because of the QC problems.

It's been a couple of years since people have posted about these tubes. Perhaps the quality has gotten better. There are similar tubes sold on Amazon but they make just be Kooka tubes rebranded.

Caveat emptor.

The gutted teleconverter route works well, although the prices of these have climbed in recent years. I picked up a couple of Takumar-A 2x Tele-Converter Reviews - Pentax K-mount Teleconverters and Adapters - Pentax Lens Reviews & Lens Database some time ago and the nice thing about deglassing them is that you can easily unscrew the glass element. Others have used a more drastic approach involving a hammer. Prior to getting these I used non-A contact extension tubes and green button metering. A little more cumbersome but it does work.
