Better XLR/RCA adapters


I know, I know, that's not audiophile way, but I might have to temporarily use them. I heard that Purist Audio is considered the best by some but they are $500 pair, and I don't want to spend $1k on adapters.
So what should I get? Cardas ? Specifically, I would use XLR cables and the current equipment is all RCA.

Just installed XLR > RCA pair, Canare L4E6S star-quad, 1M pr., $30 from GhentAudio.com, Shanghai.  Came in ca. two weeks...excellent product, ordered RCA > XLR complementary pair...highly recommended vendor.
I see. Thank you.
mitch2, there are also Cardas adapters for $150 pair. Is there real difference ? Extra $120 is not a problem if it's worth it.
I was thinking, maybe my memory was playing tricks with me. Purist adapters might be $250 for a pair so $500 for the full set.
