Here is a basic nexgen set:

I have these and I also had the dice chips. Yes, these feel, look, sound, stack significantly better. I also have used this with family. Even without denominations, beginners can still grasp what each chip is worth fairly quickly. Just use the same (standard) value each time you play and soon it will be second nature (i.e. white=1, red=5, green=25, etc.).

I might sound like I work there but I don't, just a satisfied customer who can recommend them.
