It should not be expensive at all to change the chain, that's ridiculous! If you follow a video you can do it easily... all you probably need is a chain breaker, a new chain, a zip tie and a master link (these usually come with the new chain).
I was told by the LBS that he's had trouble with the chain slipping after changing just the chain, something to do with uneven wear across the sprockets and the chainrings. I was quoted £35 for the sprockets, £25 for the chainrings, £10 for the chain and £10 for the fitting. Is the wool being pulled over my eyes here?
Also, noob question, which are the chainring bolts? There seem to be rather a lot of bolts/screws in that area...
