I have a JBL CrystalProfi 250 and love it. NIce low price on ZooPlus, really big canister volume, high quality materials and build quality and it came fully loaded with media, although I did swap one basket of sponges for some sintered glass tubes and sausages from my old external (the entire quantity of biological media from my old Sicce Genio 2 fitted into 1 basket in the JBL) with a thing layer of floss. As standard these filters come with plastic bioballs for the sediment removal area, then a basket full of porous ceramic tubes, then a load of coarse and fine sponge and finally a layer of polypad style filter pad. The claim that they come with a plastic lily pip is no longer true however, they now come with a jet nozzle (as well as a spray bar) instead. I emailed them though to complain as they still show the lily pipe on their website, and they sent me one. So good customer service as well. They also run pretty much silently (I can't hear mine anyway). What originally sold it to me though was the 4 years manufacturers warranty.
Oh and on the subject of heaters, I have a Rena Smart heater set up as the intake on my filter, and so far it is working very efficiently on the few cool days we have had lately. It's less noticeable than a normal intake strainer to my eyes.
