Well you do know what they are worth then? Reason nobody has put a price on what they think its worth is it would probably upset you. Valuing a used item is pretty simple start at new price and work backwards for age, condition, desirability, cost of spend to restore them to serviceable condition, is it current model or superseded, what year it was made, are spare parts still available, does it have a warranty etc. So start with a new MS880 that comes with new B/C & warranty & work backwards with every factor above considered. At the end of the day they are blocks of metal & plastic, don't let personal emotion hinder the valuation process, the person buying the saws does not value your personal emotion attached to an item. Be realistic, what would YOU pay for saws if you were buying them today? You really have 1 saw & a bonus incomplete parts saw to assist the sale. Price them correctly and they will sell, get it wrong or be to ambitious & you waste your time/energy. The best traders value them right so they sell fast, a saw looses desirability the longer its on the market, it instinctively tells buyers that its been over-priced or something is wrong with it. Fast sale is a good one. Be honest & describe saw correctly, good traders do this well. Really there true worth is what someone is prepared to pay for them. Good luck
