I just have had different experience with my ATP than you. I feel I got a good machine right off the bat. I'm still amazed at what it can do when comparing to other machines I own or have owned. It's still 99% as good as anything else I've swung. You have had some problems with your first two and that lead to confidence issues with it. I can totally understand that as I had similar issues with my Deus. Just hard to trust something that gave you problems in the past. To the OP, good luck on your trade. The MXT is a great machine, but you may want to look into a different coil. I'm sure the 300 has its place but as a general purpose coil, there are better options. Like Wingmaster mentioned, the D2 is a great coil. Deep & easy to PP with. It is prone to emi and can be a touch weighty but not what I'd call bad or heavy. Whites 6x10dd is what the machine was designed around and is a great coil. It'll give up a little bit of depth to the D2 but does everything else better. Better ID, less prone to emi, much lighter for better balance & much smoother all around than the D2. SEF coils get a lot of good reviews too. I've never used one so I can't comment but I hear good things!
