I have had a set of the £10 plates in the past and they were cr@p, distorted the doorskin like hell around the handles and stuck out quite a bit. Having said that, about a week after I fitted them I noticed somebody had had a go at one and failed to get in (just made the plate even more of a mess) so I guess even the cheap ones do the job. The set I have now are the £40-odd ones and they do look miles better, although as Fielder said you do still need some small files handy if you're going for the perfect fit.
