Which scale do you use?

Hey Fellers, I'm going to get a kit and wanted to know how reliable the scale that comes with the Lee Challenger is. Or do I need to get a digital one, and if so can I get by with a cheap one from a headshot or eBay? Which leads me into the main question,,, are the powder dispensor that comes with said kit reliablly consistent and accurate? Or would I still need to weigh each round to ensure match grade quality? My thoughts are if I still gotta double check and top off each round I may as well just get one of those spoon kits and a trickler..know what I mean?
