Hey I am new to bmx but ride MTB/do some dirt jumps pretty much every weekend, so i can hold my own on a bike and all. I want to get into bmx so i was wondering what bmx bike I should get. I feel like i want a custom, as completes sound really cheap. I have 300-400 dollars and ride skate parks/maybe do a couple dirt jumps/some street. I am 5 foot 8 and 110 pounds if that helps.. Thanks
