Okay, the siphoning into a bucket for water changes and gravel cleaning is a little too cumbersome for me, especially in moving a full bucket of water, so I've been looking up self-contained gravel vacuums. I've found one from Eheim that the reviews have been decent for, but it runs about $60-$80 bucks, some sites even higher. I've also found one from Hagen that's only $20 (the A-1004). Both extend the same length, and operate the same way. Should I spend the extra bucks on the Eheim, or should I go with the Hagen?
