Need 1.25" prism diagonal with compression ring

Amici,
My Lumicon finder needs to use a 1.25" prism diagonal in order to reach focus with my eyepieces. Prism diagonals from Meade/Celestron have screw clamps and are made of plastic. Yechhh.
Are there other manufacturers (other than the uber-$$$ Tak) that make quality prism diagonal with a compression ring?
Using a mirror diagonal does not permit enough in-focus with my eyepieces except with my vintage Celestron Kellner volcano tops. The ever-versatile Kellners provide lovely sharp views across their FOV, but their ancient coatings do show their age when compared with modern coatings.

Thanks. I was aware of the Baaders, but their price makes the Tak look like a bargain!

I purchased a Takahashi prism diagonal with compression ring from Opt for use with my mallincam and 6SE. Works like a charm. Model number is TFP0090.
