I use PayPoint.net with a client of mine on a magento site and found them very helpful in the setup process. However beyond this is where I was really impressed with their support.
I had various issues with our site following a server upgrade. Our PayPoint.net point of contact was extremely helpful in identifying and rectifying the problems we were having even though the problems were not caused by their module.
All in all it has been really easy to integrate PayPoint.net on magento and I would use them again in future with other clients.
