Sounds like this is your first printer(?)

Don't worry too much about multiple materials/ extruders. I have had two printers that both can do ABS/PLA. I got some PLA with my new one and haven't touched it. So don't expect to go back and forth often. Only used ABS so far.

Yes bed leveling is important and can be hard. Certain printers make it harder than it should be. On my first printer there were 4 bolts for the bed itself, and two threaded rods for the z axis. I spent more time leveling than I did

Since I only use ABS, when I went to get a new one I was focused on bed leveling. I spent 6 hours this last weekend building a MakerGear m2 and am very happy thus far. It has only one z axis motor and three bolts for the bed. Because I built it I could use my micrometer to get it close. If there is an issue as it prints, I can manually adjust the z axis as it prints.

Really cool. Highly recommend it.
