You know, I'm not sure anymore? One of the LFS's. I've seen them all over. They're about 24" long and came with plant pruning attachments as well, but I only use the gripper attachment. The tank is 30" deep and the stand is 30" so the top of the tank is at eye level so even standing on a stepladder I can barely reach the bottom without extending my reach somehow.
I'll see if I can find a link for them.
