well i just picked up a Koralia 4 because my
LFS had them for $55 (cheaper than i have seen anywhere)
so far i like it.. the flow was different than what i expected but i like it.
i think i might get another one, especially if they stay this cheap.
i still want to get a nanostream for comparison though
im trying to come up with ideas for a this pump in a video podcast, so if you have ideas im open to them
