My offer was certainly not a low ball offer nor an insult.  If I take the fact that your selling these for $17.50 and then that the picture of your farm shows half of the orbs as being without a fan and there for unsaleable in their present state on eBay it is more than a fair offer.  I took into account that I would have to solder 28 fans back onto their respectful places and then list them as "seller refurbished" or be dishonest in my listings.  They certainly would not command the same premium as a listing with the miner in good to very good condition and not having been modified from the original manufacture specs.  Assuming a scenario where the fans could not be successfully placed back onto an orb I would have been out half of my purchase as far as the resell market is concerned.  Given the fact that many orbs have sold here for $5-$7.50 and that Gawminers.com sold used ones at 5 for $29.95 I offered full retail value for what could have ended up as only 28 usable gridseed orbs.
