I'm back! lol Rim Question

I haven't built a think since 2011. I'm feeling the bug again. In 2011 I was buying these rims with tires on them for under $50.
Does anyone know of a inexpensive place to buy a 6" rim to fit a fat tire?

I'm going to take my time on this build and make it my "one" nice one.:thumbsup:

I'd like to run tires like these 145/70-6
