@sauc3 perhaps it's unsolicited advice, but the main thing I'd suggest is know what paper weight your covers are/will be and checkout the user manual for the printer you want to get and see what weights it can do via it's tray(s) or if you need to use the bypass (if it has one).
tbh the good thing is most mid-range+ laser printers & inkjets can do decent weight paper through the bypass or top-feed.
