Oops - my mistake. I meant 10 tapes. Anyway, the order's been made:
DDS4. The only way that we could afford that was if I waived my
costs. I am low on cash at the moment (next job starts in 1 month), so
it wasn't easy. I would have gone with DLT if possible.
Thanks to all for the advice - very helpful and patient.
