Thanks, Mike. That is really kind.
It is probably best to look for named ones, as the cheapest ones aren't in tune, always. As mentioned by Tootler, Yamaha, Aulos or Dolmetsch are well-known ones which will probably be fine. There are many other makes but the ones with no name at all, may be not too good.
I am not a recorder brand expert so others may be able to recommend other ones which would be ok.
