Welcome. Do you know what size pieces you’d like to be able to work? Thinking about signs, furniture, lutherie, carvings or ?
In his book on workbenches, Chris Schwartz talks about needing to be able to work on faces, edges and ends of boards. I would advise considering this when looking at machines if this may be important to you. Many machines do not allow easily working on ends of boards. Some of the aluminum extrusion based machines do allow for this. I know there are people here with Probotix (pre assembled) and CNC Router Parts (now Avid) kits that are happy with their machines.
While you are deciding on your machine, start learning the design process. With your background, you may enjoy (or be totally frustrated by) Fusion 360. The most popular may be the Vectric family - they have several levels, all have free trials.
