Welcome
Yeah, unfortunately things are quite bad at the moment.
Eastern production having been affected by Covid for the last year and a bit, shipping disruptions and Brexit issues importing means that stock is very low everywhere and most European suppliers will not deliver to UK anymore.
You can order direct from Eastern retailers but shipping is expensive and long.
Same situation on parts.
Best option right now is find something you like in a UK retailer and make sure its from a well known make but many parts are also in short supply.
