Thanks - I looked at the Rebel press, actually have one sitting here, and started working on a catcher for that one, it is just not ready yet. Buying from that guy mentioned above may be an option, I would not. He's is the worst copy-cat ever (even copied my domain name for the website to sell more) and I cannot even count how many people reached out to me to complain about his product quality - well, lack of... I'll of course post it here when I got my version ready.@The German, a member here makes great ones!
Besides that, it is beyond me how RCBS could design such a crappy primer catcher option - they had the chance to make it better than in previous models and in my books royally screwed it up...
