I am so sad myself.

I spent over three days comparing prices on a portable DVD player for DS adn DD for our upcoming trip to WDW. I finally decided to bid on two of the Disney players, a PowerRangers for DS and a princess one for DD...I finally won the two for about $150 (which included shipping) from the same seller. Insurance was not offered. I thought that was a great price since one will retail for around $130. Well, that was almost a month ago and so players in the mail yet. Other items I bought on e-bay since then have arrived but not the players. Before I bid I checked and the seller had a good rating. I e-mailed him last week asking when it shipped and when would it arrive. No response. Then, I check his feedback today and there are about 10 negative comments saying he scammed other buyers

. I really dislike having to leave negative feedback or to try to get back my $, I really want to believe this person is honest and there is a mistake with the shipment....but he never replied back to me. Unfortunately, I felt my next step was to contact Paypal. This is the first time I had a problem with a seller...I am just so sad because I really wanted the players for my kids and I dislike having to try and get my $ back, but at the same time I don't want to be out $150. Does anyone have advice on how the Paypal system works in this case? How long would I wait? Another person left feedback that they got all their money except $25 back. Thanks.
