We have the Nextiva Connect 360. We are paying a bit over $30 each month for each of our 4 lines of service. Each line of service is for one of our employees so everyone has their own number. Unlimited calling (the best thing about Nextiva) and lots of features. I don't use all of the features they offer, but having them is a good feeling. The service seems like it can support us when we hit 50 employees (which should be soon) :) We did not buy phones from nextiva. Instead we use adapters that we go from them for $55 each. I prefer the adapter because we use our cordless phones instead.
