EDI software package recommendation?

We're in the market for a new EDI solution. What do you use and recommend? We also require AS2.

Some background: A few years ago, we switched from an on-premise solution of Trusted Link and Trailblazer AS2 to a hosted solution using SPS Commerce.

We negotiated a good price at the beginning, but now that our usage has increased, they are attempting to gouge us. They offered to increase our allotment 30% for double the price we're currently paying. Yes, that's a 100% increase in cost. No thank you.

Also, we don't plan on going back to Trusted Link because of their licensing - see this thread here: https://archive.midrange.com/midrange-l/200806/msg00014.html

Thanks
