Advice for buying poker chips ?

Want to buy 500 chips. Mainly for a home games of 6 ppl, but cross my mind that on occasion more players may come. (max10)

The game will be sit`n`go type, but I am thinking at allowing a max of two re-buys per person (in the first half hour of the tournament).

I`d need your advice to get an idea of how to build the chip configuration, at what I am actually thinking is this: 4 color chip values - $1, $5, $25, and $100.

150 chips of $1, 175 chips of $5, 100 chips of $25 and only 75 chips of $100.

- Do you think is this chip configuration good, or what should I change at it ?

- Should I buy more chip denominations or any different chip denominations ?

I am thinking to buy from this online store: card-shuffler.com

- Have you ever ordered anything from them ? - Can I trust them ?

Never heard of that site but I'll give you 2 sites with everything you need.
First go to homepokertourney.com to get good ideas for just the right breakdown. They have tons of great tourney structures and once you know the structure you want to use it's easy to work out how many of each denom you need.
