I have been using Jomres for the last 5 months for a small hotel, and it has met most of our requirements. Jomres is easy to use, suitable for small- to medium-sized properties, easy to modify and customize with their templates, and of course excellent value for what you're paying. Great community and support. Occasionally some bugs but they were fixed in a flash.
Installation & Setup: 4/5
Support: 7/5 :)
Wish list: improved accounting and reporting
