In my limited experience with similar filters in the Fluval range and Rena range, I'd personally ot for the fluval, and swap the tubing over to silicone. I didn't like the Rena we had to use at the Festival of Fishkeeping a few years back.
That being said, I don't really like the fluvals that much either :?
Have you looked at the Superfish Aqua Pro 4? Also, Maidenhead Aquatics have started stocking a range of filters exclusive to them. No idea what they're like, but Luis (Ghostsword) bought one recently.
