I think Rob's got it, you don't really know how much wire your going to need. Rod's comment "you can never have too much wire" is applicable. GRJ is starting just like I started with two 500 foot reels of 14 gauge. The advice here is consistent, purchase 500 foot reels. Now think wire color, gauge, stranded or solid. I use stranded for the drops. How are you going to connect all the wires together: solder, wire nuts, barrier strips, etc. Then there are power supplies, buss design, AC or DC or both. Don't forget command control.
FWIW, I don't know how exactly many drops I have. I don't believe it's anywhere near 100. I have three (one for each rail) 14 gauge wires per drop. I have a lot of turnouts. I located the drops to minimize voltage drop and ensure continuity between turnouts and crossovers. I use 18 gauge solid for accessories, lighting, signals, turnouts, etc. I use 18 gauge stranded for controls panels since they are hinged.
