I have a press mounted to a harbor freight bench grinder stand.
Built a 24"x24" wood square top on it.
It's quite study, yet still portable.
Throw a couple thousand 75 grain BTHPs and some lead cowboy pills on the lower shelf, you'll swear it's bolted to the floor
It's also quite handy to put it in a closet when kids come over, etc.
Whole setup was around $100.
