Precision Balance (1mg) vs. Analytical Balance (0.1mg)
Either of these balances will require some care to set up. It will need to be on a solid surface away from any drafts, etc. However, neither would have the more expensive setup and maintenance requirements of say a $\pu{0.001mg}$ balance. And in either case you can take care of the cleaning and calibration yourself, particularly as it's just a hobby with no certification requirements.  

I would seriously consider looking at used equipment from a place like LabX (I have no affiliation whatsoever). I would hesitate to purchase a used $\pu{0.001mg}$ balance because that is a very sensitive piece of equipment, but a $\pu{0.1mg}$ analytical balance; my lab always bought that sort of thing used.  

You can probably get a good used $\pu{0.1mg}$ Mettler for example for the same or less than a new $\pu{1mg}$ balance and there is really no downside. It's easy to imagine you wanting to weigh out a few mg of some reagent and having the ability to do that with the extra accuracy of at least a $\pu{0.1mg}$ balance would probably be desirable.
