Let me clear up a couple of things. Depreciation does carry over, its just that after CCH bought ATX, they decided to offer a Fixed Asset Manager as a separate product, and they removed a couple of features from Max, like the asset history and now provide that only in the FA module. ATX still provides more forms than ANY other software. It's diagnostics are not as detailed as the 3K and up software, but still OK for any experienced professional, IMHO.
As for the support, I think you need to know two things. Many of us on here go way back to early days of ATX. I was a user of a 3K+ software myself until it was bought by Intuit and killed off. When I was determined not to use an Intuit product, I found ATX. What I found was a program without a few of the conveniences, but still a great program.
But what was truly amazing about ATX at that time was their people. Support was FANTASTIC. They were not only very good, they were dedicated to providing their users exceptional service. I remember one night, that first year, when I called them at 8 pm my time over a problem that I had caused. That's 9 pm their time. Tech support worked with me for 4 hours straight to help me fix the problem. A problem I'd caused, not their program's fault. Not a word about the fact that they were past closing time for support. Once it was fixed, I was ecstatic. But totally amazed that the next day I got a followup call just to make sure the problem was fixed.
They also had a process that allowed us to connect to the specific programmer for a specific form, giving direct feedback. They were extremely responsive to what we asked for. If we asked them to add a state form, for example, that they did not have, they almost always were able to provide it for us. And their Community Forum was monitored by a guy named William, that we still miss!!!! He was always there to help us, either setting us toward the right answer when we had a question or sending us to the tech person who could. It was the best support of any software for anything, that I had [make that have ever, to this day] ever known So when we sometimes gripe about the current support, it's probably less that CCH support is not good, rather that we miss the extremely superior level it had when Steve and Glynn Willett still owned it. Some of the support team had been there when they worked on the original program in the Willet's home. We compare today's adequate support to those days, and just have to gripe a bit now and then.
