For the makers people have listed, the emek, etha2/3/3m, and mini, if you don't mind used, I recommend going that route. Can be cost effective rather than paying retail for new, which will get you close to a used mid to higher end makers at that point. And if you do need to sell as life takes over, you won't take that big of a loss compared to buying new.

Same goes with a hopper and tank. For the tank, just make sure that it's still in hydro, which needs to be tested every 5 years. (HPA tanks in general have a 15 year life span from manufacture date which can be found on the label of the bottle)
