Paul I have got all the Ausi ones you have,but I bought them individually,some were 50 quid incl postage others up to 85,so you havent done too bad,especially the B and H one as that is quite hard to get for under about 100 quid incl p+p,
the last one (at the moment,there are about 5 more coming out soon!!!!!!!!) is the Dick Johnson 500 and that sells for mega bucks
