With a 1-2" sand bed, you could really deplete your sand bed, especially since the tank is >1 year. A lot depends on the quality of your live rock and sand, but it's usually safe to assume that the goby could deplete a sand bed, especially one of the heavier sifters like a Diamond Watchman.
I do not think that all the sifting gobies are terrible (I have two). The Greenbanded Goby is actually a great little fish. They don't sift too much and can be kept in small groups.
I know some like Yellow Watchman, but I've had some bad experiences with them getting very aggressive as they mature. I had a mated pair and one day my male just went insane. He killed the female, a mandarin, ripped out the eye of my Bullet Banded, attacked and shredded the fins of a 8+" Sailfin Tang, etc. All fish he had been with for over a year. Feedings habits/diet weren't changed, nothing changed, he just went nuts.
I recently bought a PinkBar Goby, and although it is technically a sifter, I haven't seen too much damage. My Yasha Goby is awesome. She only sifts out enough to build herself a little cave. She's paired with a Randalli Pistol Shrimp and are honestly two if my favorite critters in all my tanks.
The Randalli Shrimp Goby (Orange Stripe Shrimp Goby) and the Tangoroa also don't sift a ton.
My big thing: don't get a sand sifting goby to be used as a member of your cleaning crew. Fish shouldn't be considered cleaners.
That's a lot of good information.
Maybe I'll start looking at one of the goby/shrimp combos.
As far as the sifter being purchased as part of a CUC, no, I just like watching the one at my lfs swim around and sift the sand.
BTLDreef Thanks again.
