Didn't know they cost that much. I bought mine many years ago and they were expensive then but I ended up buying them from a seller in the USA as, even with extra import costs they were significantly cheaper than buying here, despite being made in the UK then shipped to the US and back to me? Was at a time when the exchange rate was very good for us though (almost $2 per £), IIRC they were under £100 back then.
Here are some cheaper ones. Depends if you're averse to made in china or not. https://a.aliexpress.com/_ExVmt3A
