Depends on cost vs the value of your house and likelihood/timing of moving. BUT I would gen up on slim profile double glazing and 'heritage' double glazing. You may find there is a style and colour you really like (things have changed a lot recently). As you are thinking about this I'd not have them seen to just now! The actual work is not to be feared - usually very quick.
