Susan,
Not a recommendation for another hoop/mold, but a comment on your situation for needing a different follower for less than 3 pounds of cheese -- I have a (home-made) mold that is roughly the same shape and size as the caciotta molds from Artisan Geek. I made a set of 4 followers, each one about 1/8" smaller diameter than the previous one, by cutting circles out of some cheap plastic cutting boards bought from a discount store. Obviously, this only works if you have a way to cut them; in my case, I used a wood-cutting bandsaw. I also smoothed them up using a drum sander, but hand-held sandpaper would have worked as well. With the four followers, I can find the one that does not allow too much to squeeze by, while still allowing some room to compress further. My home-made mold will accommodate makes using 3 to 3.5 gallons of milk, but with the smaller followers I could use it for 2 gallon makes as well.
I have given thought to purchasing one of the tomme molds from Artisan Geek. The "regular" tomme mold with follower would give me just a bit more capacity, but a different shape than my home-made mold; the large tomme mold would give me lots and lots of capacity, but it might be a tight squeeze in my current press. (Shoulda made it just a wee bit wider ...) All that to say, I'll be interested in what you wind up deciding to get!
