A Jerald show cart can go upwards of $1800 plus, a graber can be purchased directly from Mr. Graber for $1200-$1300ish or from others with a cover for $1400ish, but thats for show. You will need a sturdy easy entry or training cart to putz around in to get miles on him when the time comes. A good used easy entry can be purchased for $250-$300ish on up, if you can find a beat up show cart that is structurally sound, that would be great for putting extra miles on him. You don't want to have a show cart and beat the tar out of it (if your not planning on showing then you don't need a show cart). Whats hard to resist but is not practical for the new driver are those little mini wagons and such. Just not a practical first time cart ( I am sure plenty have them and like to play around with them, but just not a practical 1st time cart in my humble opinion).
There are tons of really cool carts, as you p[rogress you will hear more about them (the scottsman, the pacific smart cart, the hyperbike, houghtons (no longer manufactured). Lots of great carts for lots of different purposes!
