Hands down one of the best stocked record stores I've ever visited after almost two decades of collecting in multiple countries. I only got through the rock section, but 9 out of 10 of those records you always wanted to find he has. Probably 4 copies, all in near mint condition. This is not an exaggeration.
As others have said they are collector prices, but you have to step in with that mentality. The opportunity to fill so many holes in one's collection, all under one roof, comes with a premium.
I also found the owner delightful and his co-worker was very helpful at taking care of the pricing system. Expect to spend some time here.
When I find myself in Vegas I will definitely make this destination.
