Harry recommends BBD's, preferrably on a hotplate with a thin layer of oil
for maximum heat conduction. :-)

I personally *love* BBD based delays, flangers, choruses, but not attempts
at Reverb.  BBD's make horrid Reverbs, even the special purpose multitap
reverb BBDs.

The only ones currently being made are the Shanghai Belling 3207 and 3208.
Well thats not exactly true, I've found some other very expensive BBDs from
a company in Texas, but they're $90 new so not really an option.o

Anyhow, US supplier here :

Cant help you on a UK supplier.
