I used to have an Aerad subscription, but I too found the updates an absolute pain in the backside.
These days I just use the free ones. I just print them A5 size for a trip as required and find them perfectly usable at that size - and I have pretty crappy eyesight. I also keep a copy of all the UK plates in an A4 binder (2 to a side - 4 to a page) for emergency use.
