i repair monitors as part of my business,i hold virtually every value in stock at all times
in general you know that you will need
1,4.7,10,22,33,47,100uf 250v
1,10,22,47,100,220,330,470,680uf 25v,35v and 50v
that is pretty much everything covered electrolytic wise,you get a few odd values from time to time but i always order at least 20 of anything i use
