on a more serious note....
I like the first one for portability...good outside also.
The 3 tier would be sick if I had everything I wanted...but I don't so....
The last one is my overall favorite...welding table on top...just needs a vice, the only thing that suck is the size...
Maybe make one like the last one a little shorter and narrower...but with burl tires!...I don't know be creative. Hope it helped!:beer:
