Hi TheoA
I saw your post about making your own dolly and thought that you might be interested in our prices on the EuroTrax. These are $349-00 and include cradles. See them at
www.playaboule.com.Also as a matter of interest you might want to break down the "real" cost in making a dolly.
Aluminum tubing at $25-$32 a foot. x 8 ft = $200
Tires 21"x12" slick $45 to $62 = $ 90
Rims to suit $25 - $75 = $100
Bearings, collars, pins, bolts, etc?? = $ 65
Cradles $60 to $75 each = $120
Stainless Axles to suit standard rims = $ 60
Of course you can get cheaper painted steel components but then corrosion will be a problem.
Hope this helps.
