Our sister club used Atlas traps for the first 2 years, went through 2 before ordering a new Pat this year. Drive motors aren't cheap for any of them, we replaced one on one of our Beomats a few years back, the $800 hurt, having out of use for 3 months hurt worse. The nearest sporting clays club is Fredericton, most of their traps are now Promatic, they tried a number of different brands before settling on them.
Edit; I was mistaken, the sporting claysclub I mentioned is using a mix of mostly Laporte & Atlas machines, with a few others thrown in for good measure. Speaking with the course setter/Secretary yesterday.
