Jason, I made a sled a few years ago using my kids sled (see pictures), I would go with the Paris Sled if at all possible. They are better built then the one I used (mine was free- I already had it at the house)
I think REI will have them in stock in a few weeks. They have had them every year that I remember. You could call the corp. office and see if they are ordering any or you can go to your local store and special order one.
Here is how I put together my sled. It is 4 ft in length and weighs 6 lbs 5 oz including the hip belt (hip belt from an old Jansport pack) and poles (1/2 in pvc).
Here is the sled by it self

This is the bracket I used. I trimmed it down and flied it smooth. You can get it at Home Depot for about .84 cents ea. it is a Simpson strong tie "RTU2"
Belt connection, I just used a looped strap that goes through the eye bolt and the carabiner holds it in place.

Velcro strap to keep poles crossed and together. I put a rivet in one to keep the velcro in place and from getting lost
I also needed to use the sled for "sledding" after we arrived at our destination. I take the kids iglooing and they want to have some "fun" on the trip. The sled has needed some reinforcing done on the stress points (the back) because of the sledding use, kids and scouts can be rough on things.
I would like to have made breakdown poles but these have worked well for the time being.
I painted red on the stuff that I didn't want getting lost in the snow.
