Looks like the generic design in blue is pretty easy to get ahold of, and I kinda like it better than the Thomas ones lol. In addition to the ones you listed I'm seeing Mavis on eBay as well. One listing comes with a Henry tender and what appears to be Henrietta, but so far have not come across my first train versions of Toby or Henry.
