Better or cheaper?
There is a better option than 3rd party, and much cheaper. This is face to face trading. This is of course usually not an option, but if it is you should jump at the chance to trade with someone near you. Both of you get your stuff that day, and if you meet at a field, there is nothing better than testing your new gun for a day of real play first. Many regional boards have trader sections, and if you have this available to you, at least look there first as it is your safest option.
