I'm on my second CSP card now. I had the MasterCard version you can't get anymore, cancelled it, then signed up for the Visa version so I netted 80,000 points for both signup bonuses. I had the Barclay Arrival+ which is pretty good giving 2% back on everything that you can redeem for travel expenses and you get $400 for signing up, I just cancelled mine though because the $90 fee was due. I also have their USAirways card that I only signed up for for 35,000 free miles, I never use it except for USAirways flights and when they offered 15,000 free miles for spending $750 for three consecutive months. It has also come in handy for free checked bags a couple of times and earlier boarding, apparently its easy to get the fee waived on it, but otherwise I'll probably cancel it in December when it renews. I just now got approved for the American Airlines card to get 50,000 free miles that I can eventually merge with my USAirways miles. So far I have a pretty nice cache of miles saved up between programs, being able to pay my rent without any additional fee has been clutch for getting lots of free miles.
