does anyone have these chips? are they good quality?

[Colquhoun]

I have the tri-color suited ones (the second link in your post). Generally, I like them, an you will too if you are not bothered by the sound or feel of the 11.5 gram ABS chips. I also have a set of the dice chips and these are even slipperier than those. The folks I play with think they are great looking, but they are not accustomed to playing with real casino chips. If I was able to start over, I would have chosen differently...the Nexgen chips (I think they make the chips in the 3rd link of your post) get a lot of good reviews around here. Get a sample pack from 5star and go from there...
