Kudos for your choice to stay with film! Hopefully, film will stay with us!
On your search for d'room equipment, don't ignore local camera shops. Many deal with used equipment, and at great values, minus shipping.
It's important to oversize when choosing an enlarger(you may go to a larger film format later, and it's one less obstacle at that time, so plan ahead). Tray sizes are easy and inexpensive to adjust, the enlarger is the most important choice in the beginning. Recommendations as to the best choice are endless, and will be jaded by those who recommend any particular brand. Opinions are based on experience, so go with what you're comfortable with, and meets your standards.
Where to put a darkroom? I have an Omega D2 4x5 enlarger with a Zone VI cold light head, an Omega C70 35mm enlarger, printing 16x20's and 11x14's, processed in trays, I process my film in trays, mix my own developers, fixers, hypos and tone all prints. I wash my prints in an archival print washer. This all happens in a half bathroom. Be creative my friend.
