I started reloading back when I lived in a 1BR apartment, just for 45acp. My setup was:
RCBS Partner press
RCBS carbide dies
RCBS Uniflow measure (briefly used a Lee PPM but it malfed and left me not trusting it)
Lee balance scale
Lee Autoprime priming tool
2 x RCBS 50rd loading blocks
... and I think that's it.
I put the reloaded rounds into the retail ammo boxes so I didn't have to buy the MTM ammo boxes. I didn't clean the brass, ever. The stuff started turning green/brown in color, but still worked fine.
I mounted the press and powder dispenser on a 2x8 board, and c-clamped the board to my dining table when I wanted to reload.
I used this setup for quite awhile, and added .38/357, .44 and .30-30 to it while still in the 1BR environment.
By the time I graduated to .308 for my M1A, I had a garage at my disposal for my load bench. That partner press finally snapped in half one day from loading big cartridges like .308. The partner press is made from aluminum rather than iron or steel, so it doesn't take the same degree of stress that a Lee Classic Cast or RCBS Rockchucker can take.
RCBS replaced it for free, but I still went out and got a RockChucker since I had outgrown the equipment.
I also added a case tumbler once I had a garage.
The old apartment setup stowed neatly in the top shelf of my closet with no fuss. Setup took less than 5 minutes if I wanted to reload.
