A vote for Alumaweld. There's lots of them around,and lots of guides running them (and other brands too), and lots of local dealers too. If you're going to side drift, they've really got the balance figured out IMO. Don't go with a 4-stroke pump also IMO.

North River uses 1/4" exclusively???? That suprises me, as what I've learned over the years is the "inside" construction is what makes the sled tough, not just wrapping it in thick skin (extra weight)?

Shop around, as that's the really FUN part!
