If you get Jeppview, you can use the options to only print out your list of favourite airports, ie the ones you go to regularly, and then when you get new discs, every 2 weeks, it will allow you to print out only the amendments for your list of favourites. Therefore you have hardly any updating to do but still have all the plates for all the airfields in your geographic area available in case you go somewhere different.
Jeppview is updated either via a CD or online and the subscription price is around th same as for the paper amendment service so potentially your only expenditure is a laptop and a printer
