If you are looking for ease of use and do not need VoIP or multiple system networking, the DSX-160 is your best choice. It was just released last summer and has the latest technology. For example, the IntraMail on DSX is built in (only a CF card is required) and has many more features (with more on the way) than the Aspire IntraMail and IPK-II InMail. The phones and user interface are the best NEC has to offer.

Don't let comments about training and certification confuse you. The fact that a vendor can easily learn to install the product is a testament to the software design and shouldn't be considered a negative. (The DSX mantra is "Sophistication Simplified".) Just make sure your vendor has a good reputation.
