Thanks. I am a little behind on announcing OSPi 1.4 B+. We have a small amount of stock available right now, more to come next week. The option has been added to the product page, and user manual has been updated with new pictures showing the B+ version:

I still need to write a blog post announcing it. Should be done this week.
