I have used PayPal in the past and never had any real problems. I came across this link:
http://www.paypalsucks.com/ and from reading the items on this website it really makes one think about your money and where it is going and if you are going to be able to get to it the next day. I am not posting this to speak for or against PayPal, just to let everyone that uses PayPal know that apparently there have been problems with the system.
