I have a couple fairly old Penguin HOBs that are still doing well. I switched over to pretty much all AC HOBs like 3 years ago, but I have a 5-6 year old Penguin 330 that has been set up many different ways and is still going strong. It used to be primarily mechanical filtration on a couple different tanks. Now it's a biological filter on my 75, complete with a pothos plant growing hydroponically in it. I also have a couple small Penguins that are probably 8-9 years old and still in pretty good shape.
Also, as far as cycling-a bottle of pure cleaning ammonia I bought at the hardware store. When I got back into fishkeeping in high school, I learned about fishless cycling with cleaning ammonia and it worked wonders starting new tanks for me. (of course now, I just seed with media from established tanks and basically instant cycle)
