You can buy some good quality albums at ELUSIVEDISC.com. Although I will say try and find ORIGINAL used records from garage sales , friends, family, also, Used book stores, or a record convention. Most stores are getting pricey but you can still buy great records for 6 bucks or less from stores like Euclid records. ( stores in ST Louis, New Orleans)
The hunt is half the fun after all. Most new records sound like crap compared to something made in the 80's or prior. Its just to bad the art of record making is a long way from what it once was.
