The Electric Recording Co. ... thoughts on a 300 quid LP

I'm not averse to spending good money on rare and collectible vinyl, but 300 quid (or more) on a newly minted reissue? That's a whole lot of cash for 1 disc.
Conventional wisdom would suggest it is not worth it, but after repeated listening of their two new jazz reissues (Tommy Flanagan Trio and Hank Mobley) I would dare to say they are indeed worthwhile. There is meticulous  attention to detail and it is clearly a labor-of-love. I have not heard originals of these LPs, but these reissues do sound marvelous.
The only grumble I have is that some form of box/slipcase would be nice. A thick-card slipcase would make these stand-out on a shelf and keep them pristine. I would be interested to hear other thoughts on these reissues.
