Got a Calaway FTiQ Tour - upgraded shaft (forget which one) if you want? Sure we could work out a price - sub £50...?
Best all round Driver for me in this range is Ping G15
Goes for around 50-65 on Flea-Bay
There are a couple of head-only listings that will go for less if you have a 'favourite shaft' that you want to/can swap over too.
I wish, 12 degree regular going for around £100 at the moment.
We'd always recommend being fitted if you want the best gains possible, but if money is tight you're best off going for a 2013 model which will have all but the latest tech.
A quick search of American Golf revealed some good offers under £100 (http://www.americangolf.co.uk/golf-clubs/drivers/cleveland-golf-classic-xl-driver-245752.html) with plenty more probably available on auction sites, though you wont get the same product guarantees.
