Id pay whatever I thought to be decent price. it doesn matter what anyone thinks really dude. If you want to pay £50 for then pay £50.
Who is anyone to tell you how to spend your money?
I paid £80 for a limited edition vinyl pack of Grooveriders Mysteries of Funk about 2 years ago. Saw it Reckless Records in Camden last week for £16. Didnt mind one bit coz I wanted it and I paid what i could afford.
Music is priceless man and if you love it, money dont matter.
I dont think this has helped you at all!!!!!!!!!!!!!!
