Retiring engineer, looking for a 3D printer

I'm retiring at the end of this year. I started to pick up coding again and playing with rpi's and python. I used to do a lot of cad/cae work earlier in my career and 3d printing about 10-15 years ago. I would like to get a printer for home that I could use for functional parts. My budget is probably around $500-$750. I have a room that my son uses as an art studio occasionally. While it doesn't have any active ventilation setup, I could put a window fan in there to exhaust some fumes. I don't know how effective that will be though. I do home and auto repair occasionally, so having something that I could print parts for repairs (or upgrades) could be useful to me. Any recommendations.
