Just curious which IPN module people find to be the best. I've got Paypal IPN Payment Module (v0.981) installed on my site to play around with, but it's kind of a testing ground for me so it doesn't matter if I screw anything up. I've got a client who only wants to sell through paypal. I've got osCommerce 2.2-MS2 installed on their site and I've modified some things here and there, but I don't want to mess up their site by installing a module they may not need. Any advice on which is the best solution just to make sure paypal orders are going through correctly? That's all I'm really concerned about.
