I have and always will collect "raw" cards. Been collecting now for 38 years and counting. All my cards are in Ultra Pro pages in albums, with a handful of "odd" sized cards (T201, Topps 1955 Doubleheaders) in rigid card holders. I don't worry about buying raw, as I buy from 2-3 very reputable dealers on eBay, Deans Cards, and here on the boards. I consider anyone who lists in the B/S/T forum to be reputable.
This forum is a very safe place to buy, sell, and just talk cards. Love it!
