When I search the net for retailers that have the GTX RBA, a few list it, but they all seem to say out-of-stock. Anyone know where it is available reasonably priced, or is it really discontinued?
Either way, I know and also interested in a Wotofo brand RBA that also is interchangeable with GTX coils. It seems it is equally hard to find, with an internet search only finding it on Wotofo’s website…but they want $26 for shipping a single $10 item.
