Make a note of every serial number you can find on items you purchase, and note them on the manuals you get with it. Normally, a manual does not get stolen.
This way, if anyone you know steals your stuff, you can at least know who did it. Suppose your (ex)friend shows up after holidays and says he bought an R4. You can't say it's yours, but with the serial numbers at hand you can.
