To be honest, if I was a member of the viewing public and had little understanding of the cost of components, I would also think that £325 was a bit overpriced, but knowing what is included in the kit, the amount of work and development that has gone into them, the reliability of them and their ability to keep you occupied easily for ages, the price of them is pretty good.

Bottom line is that this spobby isn't that cheap to get into so you have to be prepared to invest a bit, but it's also not too shabby compared to the cost of getting into some other recreational occupations.
