i believe our fellow forumer here has his reasons for not naming the shop, so lets not force him.( if he wants to say, i beleive he will)
What he said is correct, morale of the story is to be caution of conmens and shops. This acts as a reminder for everyone, some parts/items cost that amount of money, do not get conned by misleading conmens just to save the few hundred bucks and end up paying much more for the repairs...
