I've just finished setting up Xoops for my small UK based website development company athttp://www.rwatt.co.uk , it has been fairly heavily hacked (especially the sections module), and features a programmed-from-scratch gallery script (uses the database, supports categories with unlimited subcategories). The skin is also quite pretty ;)

Customer support modules are currently being scripted, and all new modules will be released to the community once they are ready, and if the demand is there.
