Shantelly-- Hard to answer that question. You need to get prices of all the colors you are interested in... those without glass beads and those that come with them. And see what just adding the beads costs. To add it to Pebble Tech, we were quoted several thousand versus $350 for hand cast abalone shells.
One of the reasons we went with Wet Edge over Pebble Tech is that the 2 colors of Prism Matrix that were Level One happened to be the ones we liked best... so we got shells & glass beads for only a little more than Tahoe Blue Pebble Tech, which is their Level One Pebble.
We found they add to the blueness of the water and the sparkle... we added extra shell, hand cast, but our finish came with the beads. Close up photo right after filling.

But different levels of pebble, and pebble/glass blends have different prices. Ask your PB for a price list.
