For the price, Herter's are the way to go. The only bad thing about them is that they have a tendency to roll over in wind, so a lot of guys weight the keel. I know Tony Toye uses rebar on his to keep them stable. You can probably just buy some regular lead duck straps and they'd work pretty well also.
Carry-Lite's aren't bad either but will cost a little more. They just remodeled their snows last year so now they are a molded white plastic (not a brown plastic painted white)...so you no longer have to worry about the paint flaking off on them; which carry-lite's have had problems with in the past.
