No bad advice here (as usual). Pick the press you want to start with. Lee makes getting started affordable. I started with Lee and stayed with it for 30 ish years. I think there are better solutions out there, but I'd be hard pressed to warn anybody off of Lee to start.
Timing is good. Factory...
I remember the bear out front! It was right against the building in a cage. I put many guns on lay-away there when I had no business buying them. They gave you a year to pay and somehow they were able to produce the thing when you went to pay it off.
Double layers of 3/4" plywood glued and screwed together. Laminated formica on top and front. 2x4 frame and legs under making sure a leg lands on either side of where the press went. The whole thing is screwed to the wall and I truly get no movement from the bench.
Consider asking the farmer if you can hunt his field. Most farmers I know see deer as vermin. A handful of friends walking the field as a drive can be productive.
