Remember, regardless of how much you spend on the farkles, you'd be spending at least the same amount (And much more if your farkles were premium brand OEM farkles) for them no matter what make/model of bike you were putting them on.
What you should do is compare the cost of your RX3 and farkles to a similarly equipped name brand bike and farkles. Then you can sit back and feel smug about how little you've spent in comparison.
