A flojet macerator pump will work for what you're looking to do. There are three types, water powered, AC powered and DC powered. If you're only going to use it at home, I'd get the AC powered version. If you think you might want to use it "dry camping" then I'd consider the DC powered version. For me, I'd avoid the water powered one. It uses a substantial amount of water to "drive the macerator knife" and just adds to the amount of "stuff you pump through your garden hose"....
Oh, and no matter which version you get, make sure you have the "strongest vent fan available" in the bathroom you use for the "other end of the hose".... You're in for a "treat" that you'll learn to dread with every use......
Possibly, if you have a plumbing "cleanout connection" on the outside of the building that you could modify to add a hose fitting?????? that way you'd "avoid the aroma"................
