I have purchased a few Better Records but not anywhere near the price of LZ II. Yes ,I did find them to be better than the recordings I already had including one half speed master. I would not look at them as an investment and I think Better Records mentions this on their site. If you really like an album and you want a great sounding copy give them a try as there is a 30 day trial.
Led Zeppelin 11
Better Records has a just in Led Zeppelin 11 for a poultry $2499, but it's a white hot stamper!
