My view is if you pay peanuts, you get monkeys to do the work. If you want to buy or fix something always remember your choices;

Price, quality, service.

You may only choose two.

You may never find a quality item with a low price linked to good service. There is always a compromise. If you want quality and service, be prepared to pay for it. Some people may bluff you into believing that they can offer a quality service and product at a low price, but they will either go out of business or their short cuts and mistakes will come out in the woodwork.
