eheim
I have Fluval 303, quiet but harder to start
Eheim classic 2213, quiet, simple to prime, hard to damage
Eheim Pro, Eheim Pro2, Eheim Pro2thermo, nice to have baskets but more stuff to break or lose, primer is OK but a pain to lube, thermo is nice but hard to locate well in my bizarre cabinet
Eheim ECCO big and little, less flow than you expect but easy to prime just be sure to move the handle very slowly when opening
Were I to get a new canister, I'd get a Classic, simple and most bang for the buck.
