Whether X10 continues to manufacture cheap automation products probably doesn’t affect many of us here. Most of us already have fairly extensive automation systems, with spares of some of the items. And the common devices like wall switches, lamp, and appliance modules still seem to be readily available. As others have said, it is a good idea to stock up now if you have plans to expand your system in the future.
The main thing I have seen is the huge selection of cheap X10 products on eBay has disappeared. While most common devices are still available, some like the Maxi Controller are hard to find today. And prices of some products, such as the XPPF filter, have increased significantly.
If X10 has indeed ceased manufacturing, SmartHome and Leviton both offer X10 compatible products. The SmartHome dimmer module works very well, and I am contemplating replacing some of my existing X10 lamp modules with them for the additional features. All the X10 compatible wall switches we use here are Leviton, and they have worked very well with no failures over the last 8 years.
The bottom line is if we lose X10 as a supplier, there are other sources of equivalent devices. And it may benefit some of the other manufacturers still in the X10 arena. The down side is we won’t be able to buy modules for $5 each anymore.
