Hi,
Welcome to the board. It is really hard of course. I bought mine over the internet, Ebay. Needless to say I got ripped off. I can tell you this. I am not so sure I would buy a cart without seeing it in person first. Know what you want. Make sure your cart is well built, and has everything you are going to need. Trying to add on to your cart after buying it can be a pain as well as expensive. My next one I will definatley travel to see it first. My cart I have now I bought on Ebay as a,"Budget", model. There was no brand name on it. There were so many things wrong with it that I contacted the seller. Seller just laughed at me over the phone and called me a sucker. I have talked to Louie at All American a couple of times to check on parts. He seems very friendly and helpful. There is some helpful start-up information at http://www.thehotdogcart.com. I cannot recommend they’re carts because I do not own one. But the start-up info is good. Take your time, shop around, know what it is you want, and you will save yourself alot of headaches. JMHO Good Luck
