Yes, with my own eyes Martin.

It was on BBC2 I think.

And everything on TV is *always* true. Just as it is in books, newspapers, the internet...... I always remember one newspaper- things like the London Bus pictured on an iceberg in the Suday Sport- it must be true because it's in a newspaper. Or the Lancaster bomber from the Second World War which was spotted on the moon by an orbiting space probe
Sadly we all know differently.
(if anyone is interested or unsure these newspaper stories are now- amazingly- revealed to be untrue!

Anyhow, from the earlier posts it seems you must never buy the cheapest products because of issues and problems that will occur. Basic economics for the majority of people means the least expensive will often be the most favoured purchases. It might not always be the best thing for some people, but the majority will be happy- it fits the most important criterion for the majority.
Most buyers won't get much beyond basic questions and accept whatever Halfords/whoever tell them(and a lot of Halfords sales people are very young with basic knowledge of what Halfords want to sell)
Whatever people think the cheapest is what a majority of people want, so Tesco bikes will always sell- and quickly. It's not a crime, and in general most of the time the retaileer and the customer will be happy.
However there is no one right product or answer for everyone. There is room for low priced products and high priced products- both have markets, and will continue to get customers.
Yes, I see the advantages of higher priced parts- some of which may have a longer life. Yes, I have decided what I'm going to buy- a lot more than I'd initially thought- but without all those questions, and advice received I wouldnt have learned all the things I have, and understood more about the subject. A lot of people don't/won't put the effort in, and have not really thought about what they will really need. For occaisional use/ light use things probably work out ok.
Thanks to everyone for the inputs.
