Depends man... Imho the reflectors look like dookie and how old are the bulbs? Research a little on google and see what those ballasts cost when they were bought new. Take those three things into consideration, adjust for time depreciation and how old the bulbs are and set a fair price. Most people won't use a bulb past 6 months to year so if the bulbs are close or past that consider that your buyer may wish to spend more money after purchase on new bulbs
