Hi Merice46, robmoff and bromaelor
thanks so much for taking the time to reply :) I've basically got all the info I need at this stage, but have slightly changed my plan and now intend to apply to the relevant organisations... what swung it was finding out that I can get them for a lot less than the £27.50 I thought each would cost.
I live in Ireland so it will cost that little bit more... but for the sheer thrill I think it's worth it!
Had a great couple of days researching... it's addictive!
Again, thanks to all of you for your advice and help.
