I bought one from Harbor Fright because of the price. It serves me well, I use it mostly on my medium sized 12X8 enclosed trailer. The low part isn't a big deal because you have to crank the wheel a few times with any dolly to get good clearance. The HF one isn't so low that I can't use it, and I haven't had any clearance issues. Besides, I don't feel bad leaving it outside if you know what I mean. The HF one is probably 1/3 to 1/2 the price of competing models so I am willing crank the wheel a few more times. But I use a 2WD truck so if you have a big lifted 4X4 3500 you may want to spend a bit more coin. However, I think there is something like a 24" recommended max height for trailer hitches anyway so the cranking distance may not be that far. I could measure the assembled height of mine if you like.
