Bore gauge - to borrow, rent or buy

I am ready to start assembling my 440 budget build. I need to measure the bores, and I don't have a bore gauge. No one I know owns one, and I don't want to spend a fortune on a tool I will use once in my life. I can buy a China made piece of junk for $50, but then I wouldn't really trust it, and again, I would use it once. Anyone have one they could borrow or rent me? Or a decent one for sale at a decent price? My brother says to look for go-no go gauge set, but damn! They are expensive. Any help would be appreciated.
