Again I've never heard of the brand, but if Newegg offers it then I'm sure you could always return it if something was wrong with it.
The issue I have with off brands is the return policy/warranty from the company is never as good as it is with a brand like Sony or Asus. So for that reason I recommend not buying direct from the manufacturer on things like this as the retailer will impose their own warranty on top of the manufacturers.
The specs in that one don't look half bad though, and again, Newegg will reimburse you if something is wrong or if you aren't happy with it. I say go for it if that's all your budget can allow.
Yeah, the transaction would be through Amazon itself. Personally I don't use Amazon at all, so if you have any other questions about their services you're better off contacting them directly to inquire. They have a help forum you can find here that you can post any questions on regarding their services.
