I am in the same situation you are, I put money into my Paypal account but there´s still some sort of feeling that Fanatec would be a bad choice. I remember when I ordered the GT2 wheel in december 2010 and it came as defect, couldn´t use it on my PC but worked on consoles, however I got no problem with the Fanatec support, they responded within 5 days and gave me my money back and allowed me to keep the defect wheel.
What makes me lean more towards the CSW is the rims wich Fanatec offers, they look alot better than the ones offered by Thrustmaster and the CSP V2 are also of much higher quality than the pedals that come with the T500, but of course they do work with T500 if you play on PC but I wish there was an option to buy just the T500 without the mediocre pedals.
The T500 allows custom wheels wich CSW doesn´t allow and in a comment about his review below, the guy who compares them says the BMW rim is heavier than the custom GT rim he put on the T500 (probably becuse of all the onboard buttons and LCD display). The quick release of the CSW doesn´t mean much to me as I only plan to have one rim and I am not interested in F1 where the CSW have an edge over the plasticky rim offered by Thrustmaster.
The last con of the T500 is the fan wich I read is as loud as the Fanatec Porsche wheel wich makes me very concerned since I really hated the noise of the fan of the Fanatec Porsche wheel, but in the review where this guy says it is very loud he doens´t mention the version of his T500, I guess It´s the earliest one from 2011.
