I buy the MFSL sleeves from Music Direct, and I have never had a problem. They are somewhat expensive, ($20 for 50),but if you buy them in bulk, the price is fairly reasonable, (200 sleeves for $60, I think, based on memory).
FYI, I have bought some used records before that did have some generic sleeves that were, for want of a better word, "warped". It was annoying enough that I threw them away, and replaced them, so I can see where you are coming from.
Good Luck!
