If you want a project camera (the ebay one you mention looks quite a lot like a "project") you can have my Korona 8x10 for the shipping... But that also needs a handy-man. I don't have the time or resources for it now, and I'd rather see it working than gathering dust in a corner.
I think wetplates is a "bit" more involved compared to normal LF, so if I would do it, I'd start out a bit smaller, 5x7 or 8x10. They are slightly easier to handle.
