Sorry cap, but if you follow the link, you'll see that it's EXACTLY that at one of the largest A/V retailers for the broadcast industry on the web!
(the link is the price by the way, click on it and see)
I typed it into google and took the first result... I didn't shop around or try to make it lopsided... I took both products form the first retailer to appear in a fair search. I realize that prices vary, but again, first results on similar items from the same source.
Yes, oh yes, your magliner is superior to every other wheeled device on the planet, but it's still too expensive when compared to a similar product that still lasts for decades (as proven by my own personal use).
Since few DJs stay in this business as long as either one of us have, a cart that last well over ten years is quite suitable. The selling point of the magliner lasting long enough to carry your casket is not what most people take into account when they want to ferry their gear from A to B!
The new tires on the R'n'R cart have addressed the flat tire complaint, the welds are good, the steel is strong, and some of the money is still in your pocket... and we all know how cheap we are as a collective industry!
The original postulate was regarding the Rock'N'Roller Multi-Cart as compared to the Ultimate Karma Kart... The Rock'N'Roller Multi-Cart is the superior product in that contest. The Magliner may well be superior to them both, however, it wasn't part of the discussion. Blake didn't ask an open-ended "which cart is best" question, he asked a very specific question and got specific and pertinent answers from everyone but you.
