Upgrading to better welder

I’ve been welding with my dad’s old AC buzz box for a few years now and Im ready to upgrade to a DC welder. I’m not necessarily looking for anything brand new and fancy but I’d like something I can use in the shop as well as the field because I fix a lot of farm equipment. A stick rig is preferred as I mostly weld thicker material but I’d consider a MIG unit or one capable of running MIG. Any recommendations?
