This is Paul Volcko. I work with Neil on the Coal-Trol (the software in the thermostat predominantly) and I'm a part owner of the company.
I'm not sure which system you were looking into buying, but the Coal-Trol Digital Standard and Standard+ systems are shipping currently and the Coal-Trol Digital Basic and Basic+ systems will be shipping shortly. We're also in the middle of updating our web site. By the end of the week we should be ready to switch it over to the new pages with the new products and information covered.
We're more than happy to answer any questions or concerns you have. As you've talked to Neil already you must have our number. Feel free to call again with any questions or ask away here. You can also email us at email@example.com
