That sucks bro. I know how you feel....I've had valuable and non-valuables taken from me from family. It's usually the ones that take advantage of others and feel that your "family" it's ok to "borrow". Does your uncle live with you? Is there a way you can pay him a "visit" and scour his home? Be patient and plan it out. A system nowadays is a whole paycheck for a 20yr old. Be patient. I hope it works out.
