What is the most affordable meeting room booking software?

I want to start a discussion based on the overview from G2’s Meeting Room Booking Systems category.

And here’s a list of products with feature-focused descriptions:

• Roomzilla: Lightweight room reservation system, supports Google/Outlook calendar integration, ideal for small businesses looking for simplicity.
• Skedda: Platform for room and desk booking with map view, good customer support, strong for hybrid office setups.
• UnSpot: All-in-one booking for workplaces and meeting rooms, excellent UX ratings, free trial available.
• Joan: Device-agnostic room booking + desk + visitor management; good features for integrating with calendars; slightly higher cost in some plans.
• Tactic: Hybrid workplace solution including meeting room booking, desk booking, parking space reservation; starting low entry price noted in free/affordable list.
• Archie: Office management platform with meeting room booking + desk scheduling + employee presence; strong user satisfaction.
• Appspace: More comprehensive workplace experience platform (rooms + spaces + signage + visitor management), might be slightly beyond “most affordable” if features are extra.

Which affordable meeting-room tools have you used, and how did their cost-versus-features balance hold up? Did implementation, hardware, or integration fees turn a “cheap” option into something pricier?
