Hi Rosie
May I suggest that you try Lidl supermarkets? You have to keep checking but every so often they have really reasonably priced NOIDs including Dendrobiums of the phal type, in November they had Cymbidiums and in December they had some Cambria types, Zygopetalums and I swear that the Odontoglossum was the same as the "Anna Claire" I got from an Italian nursery.
I know its nice to have names, but in the end its also good to give a supermarket pot plant a home where it won't be consigned to the bin when all the flowers are finished.
Also do you have a Stephen H Smith garden Centre near you - I got two NOID paphs from them, I had the first one as a gift when in flower then went back and got the second when the flowers had dropped and it was half price!
Happy growing - your plant is beautiful
