I got a pair of Nets/Minny tix for the 23rd from Tickets Now.com. I highly recommend them because they were reasonably priced and sent the tix asap. I'm not sure how stubhub's pricing or surcharges are but Howard Stern gives them mentions on his show all the time so they can't be all bad.
i've used stubhub many times, and it works rather well. The only thing is they charge a certain amount of money for commision. Also who sells the tickets usually jack up the prices to make money. I've overpaid many times for giants tickets, but i like the security of knowing ill have tickets rather then scalp. Generally if they are sold for cheaper its someone desperate to sell the tickets, sometime season ticket holders who cannot attend the game will try to sell them for what they can to get some of their money back.
