Wynne
You specify what f-ratio, filters and chip cover slip thickness (used for optical back focus calc) are in the system and ASA calculates the depth for the custom spacer/adapter which goes between the Wynne and the specific camera/CFW. ASA hava a spreadsheet for this purpose on their website. These systems require a very large secondary if you wish to fully illuminate a full frame chip.
150 euro for an essential adapter like this is quite reasonable when compared to the price of the corrector itself.
If you are planning to hang a large and heavy CCD camera and filter wheel off this Wynne you will need to have a very strong base connection for the focuser to avoid flexure.
