If you are going to get something, get a press. From what I have seen on here, the least expensive press you can get will run around $150. I understand Feather Ridge makes one in that price range,...don't know about others.
As for jigs, I would not bother with getting one. I have one,...have not used it in years because it is easier to make calls without it and it is very limiting as to what you can do with it. You would be much better off just making calls on a table.
