From the dealer my guess is around 2000.00..most come "ready to paint" however I'm pretty sure you can have them factory painted not cheap, check craigslist or fleabay..I had some on my deluxe that I bought at a swap meet and had them painted to match my bike I had around 900.00 in them..
craigslist-paid 200$ for right and left with all the hardware. Picked up cyclevisions kit to mount them. painted them myself. total investment-right around 450-475$
if you can find the latest iteration of hard bags on ebay.. youre a luckier man than i.
i insisted on police bags cuz i wanted the one hand open out feature of the new hard bags.. i did find a mint pr for 240 i think.. on CL.. then theres the brackets.. limited options for a good set
