FWIW I fitted a set of Fender Original Vintage pick ups to my Affinity Tele. I bought that for about £99 14 years ago and the pick ups must have been close to £100 7-8 years ago now. They certainly cleared up the muddy neck pick up that the Affinity had, though I've since moved them onto a MIM 50's Classic that I bought locally off Gumtree last year for half the new price. I'm going to convert my Affinity Tele to P90s so they will probably cost more than the guitar did when new, but it's not worth much if I sold it and it's nicely played in now after 14 years. The orange drop capacitors are a particular type that seems to have mythical properties according to some, though IMHO it's the particular value that you fit that makes the difference. You can buy them from Bare Knuckle in the UK (who also make pick ups) if you want as they aren't massively expensive.
