Digital BW, The Print

Hello

I still use PS 7.0 As I have retired, I am no longer entitled to use
the educational versions and I should like to buy an OEM version of
Photoshop 
CS (Actually I could do with the PS part of CS).

Prices are exorbitant for a private person in this country.

Question:

Are they reliable? Any further thoughts? Thanks!
