Puppy,
Many of us clicked on the "try buying manager link" when it was first on the AS board. For most snipers you will pay double, I think it has conditional groups and benefits that AS doesn't have but the main thing it doesn't do is snipe and you pay a fee on every win at eBay whether you use BM, AS or manually bid (anyway that was the rule back in august).
