I usually frequent FNS once every couple months and there are a few tables with decent to good bball, depending on what they've gotten. Unfortunately there are no quality LCS' in the Pasadena area where I live. The only ones I've heard of that are ok are the ones you mentioned.
There's also Burbank Sportscards, supposedly the largest warehouse of cards on the west coast, but customer service there is terrible.
Please have the common courtesy of following through all negotiations.
