Hi barbersdrove. what a brilliant idea for a birthday pressie .As advised in previous reply it is best to look before you buy as there are several types and prices vary considerably. It is worth looking through magazines such as Country file ,Rspb Birds or Bird Watching . Vine house farm is fine as they are local and the owner Nicholas Watts is extremely knowledgeable on bird watching. The Wild life group has on many occasions dealt with a company called Natural Surroundings of Holt in Norfolk who supply all manner of wild life sundries, it would be a good place to visit as they have usually got one or two up and running wich you could see and get advice at the same time. They also produce a good catalogue of thier products. It is best to ring for opening times and request a catalgue at the same time. the centre is set in a lovelly wooded valley but if you do visit try to pick a nice day as it can be a little wet.
