P*ynes have plenty for sale. You can buy exactly the same thing from WPF (at a considerably increased price?). M*dern B**keeping do Langstroths in deep and jumbo versions. Th*rne do them in Timber. I'm sure Hivemaker or Tom Bick (both on the forum) would make you a first class ready-built item.
In fact, lots do them - just this bloke was an advertiser on the forum, not a beekeeper and was likely (gently?) told to sling his hook.
