My father started collecting when I was 10, and soon after I caught the bug as well, I'm 26 now. Growing up through school, I bought what ever I could afford, whether it was a $10 can or $100 gas pump. Buy he time I wa 18 I had enough junk to fill a building, so I started to sell. One mans junk is another mans treasure, so buy anything that is in good condition and cheap, even if you don't want it. There is someone just like you trying to start thier collection. I have also found on big buys on items that you would probably sell, find a partner that will goes halves with you. You will both make some money, and you have someone to hunt for this stuff with.
