Thanks guys for the help. I eventually went for Nightmare City (missed your posts) as in HMV it was down to £14.99 as they had labelled it incorrectly, I also had a couple of quid off that so not to bad.
I will see if I have any spare cash for A Touch Of Zen next week.
On second thoughts I should have gone with ATOZ as it might have gone OOP by the time I can afford it.
