They certainly are - only 3 left (7 sold) now. I don’t want one though. (Though I see they have it in two places in their online shop, so maybe they actually have more.)
If anyone is thinking of getting one, do remember efficiency is about 50% at best, whereas gain is large - you need less than 10mW in for the full output! So maybe not the ideal solution for /P use, but the excellent value and ease of use might outweigh this when you consider a new FET for a 2m PA will set you back £30 or so.

Thanks for the tip; worth a try. All adds to the experience, whatever the outcome.

Or less than £5

Thanks Richard, the RD15HVF1 looks interesting - only 15W though, you’d need two of them! I’ve saved the datasheet should I ever want to build another 2m linear.
I used a BLF245 which is a 30W device from Farnell, hence the cost!
