If you are first time User of Online Shopping. Than you can buy from ebay. If you are not satisfied from product you can claim under ebay guaranty. Bad things about ebay are
1) If you are related or live any villages than you will got your product very very late.
2)After claimed you want to claimed in your bank account than it can be 70 days. Currently I got in 70 days.
So, if its ok with you. You can buy from ebay.
