Exactly what do you need/would like? If you can post that I can narrow it down for you :P
EDIT: I'm sorry I missed a key-point of your post.
(By the way the correct address it
http://www.allinchips.net/ but its no biggie ^^)
The all-in chips are very slightly better than the normal 11.5gram suited/dice chip, while they would be an improvement to what you use, they are not worth the price.
The 11.5 gram "clay" chips are not the real clay chips. They are made with a metal insert. You can get a set of 1000 for around $140 with no shipping or $104+ shipping (whichever is cheapest)
The next step up would be these

I would recomend the clay chips with edge spot as they will be unique to your game( well basically)
The next step up would be Chipcos I guess. I really don't like these chips though. For the price you could get a colored printed center at pokerchips.com
The final step would be a set of paulsons.

They dont make paulsons anymore so they are hard to find.
Another choice may be something like this:

made by bluechip im pretty sure. Good chips but maybe to pricey. For this much I would much rather get a clay chip w/ edge spot from pc.com but whatever
