I slowly worked my way up by buying things for a slightly lower price and then selling them for more. some good examples are certain stranges, paints, and some hats/miscs. Once i had a bit over a bud (~ 1.2-1.4) mostly in keys and metal i bought my first unusual. (A stormy storm dapper). It takes time and patience if you not going to buy buds/keys with real world money.
