The sorbent ones aren't that great, price-wise, for the amount you get - at least when I've looked at them, they are about $4-5 for 40! But, yeah, they're flushable.
The Nappy Lady (who has the online shop that was called DashX - she recently changed the name, but it redirects anyway) says her flushables will come in late May/June, so I'm waiting for those!
