The work bench should do the trick. If you have a Menards home store near you, they have a store brand " work mate" for under $20. (under $15 I believe, but not sure) Anyway, the sandbag idea should work. What I would do is get a solid 2x8 and mound the press to that. Then all you have to do is set up the work-mate, put on the bags or stabilize it w/ something and clamp in the board. Sound like a good range reloader as well. I have seen these used for shooting benches as well. Good luck!
