"So, if the issues are corrected, how would one find out, without purchasing and hoping you got a good one? "
If it were me before I took another chance ( I wouldn't) I'd call the dealer I bought it from and ask what their present take on the quality/returns is. I'd also call a couple of other dealers and ask the same. I would preface my question with the fact that I have had to return 2 of them already. I would not discuss with them the responses received from Project as to not prejudice their responses. Compare and contrast for yourself the dealer(s)' and Project's responses; and then decide whether or not you want to take another chance.
