Most vegas casino tournaments use chip values 25, 100, 500, 1k, 5k. It's very standard, and it's nice to use a familiar structure at home games, as you'll be on familiar territory if you go to vegas. I find "weird" starting stacks or chip values frustrating.
A typical 5k stack will be 8*25 + 8*100 + 2*500 + 3*1k. Throw in a 5k to get a 10k "deep stack" tournament.
I have these
chips for my home games. Paulson is the best and is used by many casinos. I use the 1s and 5s for cash, like casinos do.
BTW, it may seem strange to start tnys with 25 chips. The reason for this is that you run your 1/2 and 2/5 games with the 1s and 5s so there's a clean separation in chip denominations between cash and tournaments. Typically blue = $1, red = $5, green = 25t, and black = 100t. Above that, colors often vary.
