Looks nice, I jumped on the Dale's rack as I thought it would take too much time to get the design done and written to a DXF file to cut. (I am lazy)
3/16 steel should be strong enough compared to a 3/16 aluminum as used in the Dale's rack. It has been said a Dales will support in the area of 40 lbs.
On a different note, water jet is the cleanest cutting method but my plasma table with the correct tweaking does pretty nice also.

I am gonna set my rack with a tour pack for the misses, so the fugly won't hurt too bad
