I bought a complete set of RG tins (no tourpak) in 2011 for 1500.00. Front fender, rear fender, side covers, tank, outer fairing, saddlebags and lids with hardware. I still have the tank in '04 scarlet red with silver stripe.
I have amassed a 3rd set of tins in various colors now for a future paint project and am into that set for about 780.00, I still need an 08 up fuel tank and an 08 down rear fender.
If your original tins are a one year color it makes sense to keep them in original condition imho and find a donor set to paint the color you want.
