I'm using 100% play sand in one tank and it's not bad. No compacting over time, and Malaysion Trumpet Snails help keep it stirred up. It's very sterile, though. And it won't accumulate mulm like most fine gravel will since it is relatively tightly packed. Most debris settles on the surface, requiring frequent cleaning to keep it from looking unsightly.
It's definitely useable in a low-budget tank, though.
