I bought a clear snap on case for my Mytouch 4G and received it in the mail today. It cost me $3.00 on eBay and T-Mobile sells them for $30. Here's the kicker though, the case I bought won't even stay snapped on my phone, it keeps coming off on the top left corner. I've bought accessories for my devices before from Amazon and eBay and this is the first time I've had problems. To answer the question, if you want a quality accessory, go with what the carrier has in stock, if you wanna take a bit on a gamble then get them off 3rd party websites. You get what you pay for.
