cartridge alignment?

so i have everything i need finally to get my 1st system up and running, yet, i have nothing to align my cartridge with, and i have no idea what to get. when i talked to the guy at united home audio, he mentioned a wallytractor, or something to that effect, but said it was like 300 bucks, where i was looking to spend around 50. if anybody could make a suggestion in that price range it would be greatly appreciated
