Wanna start racing. Which buggy?

[Benjab]

Hello. I wanna get into racing so i need a buggy. But i have no idea which!

Here in Denmark there is a b44 for sale without electronics but with a saddle pack battery its 145 pounds.

There's also a b4 for sale. It has some aluminum upgrades: Front and rear a-arms, threaded shocks, t-piece, front tower and gearbox. It comes with a atshushihara esc (never heard about it before) and a 17x2t motor, sanwa mx-3 radiosystem. It also comes with some 4600 mah nimh batts. Also 2 front wheels with tires, 2 rear wheels with tires and 2 rear tires. Its 182 pounds.

I could also buy a ansmann mad rat, extra wheels and tires, extra wing and bearing set for about 70 pounds i think.

I have a velineon esc, 3 brushless motors: 12t carson, 10t carson, 8,5t ezrun and a pretty cheap radiosystem so if i bought the madrat or b44 i could use my "old" electronics.

Can you help me decide? Im just a kid so i dont have plenty of money

My english is not perfect but im sure you will understand me
