I believe that BC557Bs are considered a suitable 'drop-in' replacement for AF117s, but I've not had cause to try them.
Nothing ventured - nothing gained, so you might wish to have a punt on them.
They do have the merit of being very cheap - as in £1.78 'buy it now' for 20 post free from here:

Best of luck in your endeavours - we feel your pain!
