I have an old Raleigh Record that I'm considering either fixing up or scrapping for a new/ "new" used bike. Bought it about 10 years ago and fixed up but over the years and a couple of seasons being kept outside it's starting to show. The wheels need to be replaced, the gearing doesn't work well, neither do the brakes. Still ride it to work a lot of the time but it'd be nice to have a more comfortable commute. Just was wondering if you think it's worth putting money into fixing and also time which is even more of an issue. Does anyone have an idea how much it would cost to get my LBS to make these changes? I live in NYC so expecting $$$. I'm looking to spend no more than $450. Also, does anyone have any recommendations for which parts to replace mine with (derailleurs, crankset, wheelset)?

current components:
-Shimano SIS rear derailleur
-Hurel front derailleur
-Nervar crankset
-SunTour gear shifters
-"centerpull" brakes
