I've been looking through the ads lately, and I see several common denominators in may of them. Dirty equipment for sale and other things. Dust, fingerprints, rigs piled on top of the item for sale, some just plain nasty stuff. Then there are the ones that have scratches, dents, etc. which weren't mentioned. Then, the ones with 1 picture, no serial number, or how old it is, original owner or not. Many have the same old same old, no mic, power cord, manual, original boxes, etc. One thing that should be mentioned in your ad, if you want to sell it only, put NO TRADES, as I have noticed much time wasted with people offering trades when the seller didn't say so. Lastly to buyers, if the seller says contact with questions by email, then do so. Just trying to help.
