I read a bit about Riverfront teaming up with Concept many months ago but haven't heard much since. The webpage is pretty bare-bones, has anyone been around recently who can comment on the current state of things?

How do they compare to Pisces in terms of selection/price?

I recommend drilling multiple holes so you can use a quieter overflow arrangement (Herbie?). You could also drill the side/back if you suspect the bottom is tempered.

Go for cast acrylic over extruded when possible as well. The extruded stuff is much softer and will absorb more water.

I had one a long time ago.

The main problem is that there are virtually no advantages to a fluidized bed filter. They don't achieve anything that a basket of bio-media doesn't do just as well. If you really need more filtration why not just get another canister?

You complicate the plumbing and put yourself at risk of blowing a cloud of sand into the tank or filter.

The textbook advantage of a fludized bed filter is efficient space usage, but the extra plumbing you need will offset that anyways.

I'd take a sump over a fluidized bed no question.
