Ditto....don't waste your money on a cheaper one. I use the "GG-40" from J Thomas. To make a garbage bag for the trash, I put one loop of a plastic grocery bag over a control stick, and the other loop over my seat adjustment. Using this set-up I never have to get off of the mower.
I also made a very simple holder for the grabber to keep it out of the way and safe from damage...I'll try to post a pic if anyone's interested.
