I did not start this thread to put anyone off ebay. It is a fantastic resource if used sensibly. I've bought and sold literally thousands of times with only minor issues. I've also bought or sold perhaps 20 items in the £1k – £2k range unseen with no real problem. (Sellers being a little economical with the descriptions of condition is as bad as it gets).
I was a police officer most of my working life. Like most police officers I can be overly suspisious and cynical and I don't believe in coincidence!
A new seller selling a high value item is not in itself a reason not to buy but with all the other contra indicators; recent feedback for low value items, short duration auctions with the item in a remote location (How many people reading could get to Dunoon to view within the time constraints of a 24 hour auction?) BACS as payment, refusal to accept paypal and the biggest one, plagerised description and photos.
Ask the seller an awkward question or for a photo of an obscure part, something he won't be able to get from the net, say, the underside of the tail stock. A genuine seller won't mind. I've run down the garden to my workshop in the middle of the night with a camera and tape measure in order to answer questions before now.
All that being said, I've had some real bargains from new sellers, just be carefull, go with your head not your heart. If it lookslike a duck, waddles like a duck and quacks like a duck, it's probably a duck.
