Pro Bmx Bikes

I Have One Of Those Bikes Walmart Bikes (sadly) And I Want A Good But Cheaper Pro Bmx ( Money Problems). I Want One Because I Met My Friend In Town Today And All The Stuff He Was Doing Was Awesome. I Would Never Be Able To Do Any Of That On My Bike. He Was Doing Wheelies And Things And They Looked So Easy For Him. Also What's The Best Pro Bmx Bike Company?
