The Trioplan 100mm with M42 mount is easy adaptable with a M42-EOS adapter. The version with Exakta mount is more problematic, depends on the adapter, camera, and wheter you need infintiy.
This results in different Ebay prices.
A quick search tells me i will need to be patient - no shortage of Exacta mounts for sale, but M42's come up quite rarely. And they aren't cheap either
