Thank you for the great referral to Waterline Systems! I tried their web site and discovered that:
(1) they moved to North Kingstown on December 17​, and
(2) there is a glitch in their ordering system that rejected my order because of a problem with the 'method of payment' not being accepted for my state.
I left a voice message and an e-mail message asking for help in completing this order (they did not answer their phone) and am assuming that they are struggling with set-up issues in their new facility. But it does appear that they are still in business - more on this later, after I (hopefully) hear back from Waterline.
