how much to sell an advance diy vho system for??

[Lunchbucket]

i made a diy vho system for me but my tank would get to hot i believe and for LPS and softies 2vhos and 2 NO's would be sufficent so i am planning on selling it to a fellow reefer in town

how much you think i should put on the system:

advance ballast, 2 sets of endcaps, prewired w/ heavy heavy extension cord, diy standoffs. everything but bulbs for a 2 vhos system.

thanks
