Where do you draw the line between a demo and a used piece of machinery. i purchased a demo etesia pro 53 LK (sight unseen) through a reputable dealer and have been looking forward to collecting it and putting it to work. However when i went to collect it earlier, it certainly had been demo'd. worn bag, stiff height adjusters and a deck that had met a few to many stones for a walk around the park. At less than 20% off the list price, the bargain quickly lost its shine and i came home empty handed. From what i read here they are really good and my new pro 46 is excellent. What condition should i expect from a demo and with a list price of 2640 vat incl, is £2140 too much. Any advice would be much appreciated.
