Hello all, this is my first adventure into having my own welding equipment, and my boss has a Miller Sidekick. It's a used 110v mig welding and will include a cart, helmet, manual, gloves and everything except for a tank. It was new in 1998 and was used by the local tech college for 3 years, and seems to be very well taken care of. He just told me to offer him a price, because he does not use it any more. What do you guys think would be a fair price??

Many thanks!!
