I have a Herpstat ND, a Herpstat, and the Hydrofarm. Also, years ago had the Big Apple Herp proportional (the big white one).

I LOVE my Herpstats, but ended up picking up a Hydrofarm as a temporary measure because of waiting on a slow to ship vendor, and where I live they are sold locally. That said, I have no complaints with the Hydrofarm, it is what it is.
