I think that there is a lot of confusion with the prices some sell their rounds, is the 5x only for the customers or all the equipment.
I know that if I sold my round lock, stock and spare connector it would easily achieve over 10x, even if I broke it up and sold in parcels it would still achieve 10x or more.
It all comes down to what you are selling and in what condition it is, what type of customer do you have and what are your prices, and also how keen you are to sell or more importly how keen is the buyer.
I sold a market stall business some years ago for a very high price, I had many who tried to knock me down in price, but why should I, I was in no rush and I was making money every week while it was not sold, so at the end of the day a guy came up, saw the potential as well as what it was already doing and snapped my hand off.
