I have the HLA 2000 and it has oscillation but does not have float and for me that was a real problem. My driveway is gravel, with lots of ups and downs (humps, dips or whatever you want to call them) and without float it was a nightmare to use the plow. I ended up coming with a way to make it float and now it is much easier to use and it does a better job. I've watched a few of Eric's videos and prefer his Hiniker plow to mine. His has a built in float and it seems to have a better trip mechanism. His trip recovery doesn't bang back up really hard, like mine does. I know the trip is adjustable and I have mine set very soft but it still bangs up hard. I believe it is the way the Hiniker springs are mounted, that make it recover softer.
