I've never paid full price for any of my bigger filters. I bought one of my two fluval 306's for about $80 last year when petco had that 50% coupon that went viral (and was later kicking myself for not grabbing the 406 instead), the other I got on ebay for about $63, and it shipped to me from... Petco! I feel like what I paid for each was reasonable.. full retail, not so much.
So far I can say that the flow from the 2217 is really impressive, but the priming to get it going leaves a lot to be desired. I also wonder how difficult will it be to clean it out when the time comes? The fluvals are super simple with their trays.. but I forsee a small collection of buckets in my future for the Eheim.
