I've got a 1200 and it works well. However, last spring while I was planting corn and milo the transmission kept wanting to jump gears. I've used it for around 6 years and this was the first I've ever had to fight this issue. Haven't torn into it yet, but that will be a project after the new year. The factory electronics work wonderful on larger seed, but smaller seed such as milo the sensors have a hard time monitoring seed as they are dropped and I get a lot of false blocked row faults. Keeping just the amount of required vacuum is essential for population accuracy, this is something I've learned with experience. If the book calls for 22"-25" of vacuum, I try to run closer to the upper end but be careful not to run over it if you can, this will aid accuracy tremendously. I use mine for no-till into wheat stubble and I don't use any row cleaners or trash whippers and haven't had an issues with hair pinning. Overall, they are nice planters but with any planter you will want to keep a few extra parts with you for in field repairs. I haven't needed anything other than closer bearings and a couple down pressure springs. I've planted in some conditions where the ground seemed like concrete and I've never had an issue with getting proper seed placement. Hope this helps, wasn't sure what type of answers you might be looking for.
