I use the coinpayment.net gateway for payments and only have good things to say about it. It has an option where it will forward payments automatically to your preferred address as soon as the transaction has 3 confirms so you do not have to keep your coins on their site. There are fees but the pro's are worth it.
I also found that it triggers the stock manager correctly which makes running the sales much easier.
Still liking this idea
All the best
