I know you have located a suitable SSRr .Crydom are very good, but they suggest you run them at 70% their rating.The Fotek on ebay are fine.I use them often and havn't had any problems.Maybe I'm lucky, who knows.But a word of advice when buying on ebay.If the device or component your looking at is from a seller that also sells other crap that isn't remotely associated to electronics ,you probably want to buy from someone else.Their are plenty of dedicated electronic suppliers there that have very good reliable products.
Anyway, good luck with your project.
