I got two robustly built APC units for $5 at Goodwill. They would have been that each, but it was half price day.
It seems big companies throw them out when the batteries fail, and here, batteries tailored for this unit are about $20 each on't net. Not much more from APC. Hopefully, someone in the UK would be able to offer such prices if you happen across anything used.
I imagine having to fit 13a outlets is quite an investment for the makers. It certainly would soak up the available panel space.
I put this ramble on JB for the less serious-minded Ppruners.
Edit to say, I'd forgotten just how funny the Pixars 'Alien Check Ride' was, a few posts down.
