Ron, good luck with it. In relation to sizing I have found that my wader size of XL is pretty much XL anywhere I go, and the four odd pairs I currently have are all XL. It is therefore not an issue for me to buy them on the web, unlike the boots as already posted.

Re felts, I think nothing beats them. As correctly noted previously felt is now banned in New Zealand so I got some Simms Aquastealth and they come pretty close though. Anything else I would not even consider. Some of my mates have and ended up wet as a result, happy not to be dead.
