Gamma cards

[Top hat]

Hi to all of you tech guys, would like a little advice please.
I currently have a TM6900 Super. I know lots f the original channels have been encrypted beyhond hacking and am wondering, if anything, what i would gain by buying a Gamma card.
Is it hard to program?
Do you know a where they can be purchased, i know lots of places are advertising but as they are saying no comebacks, some may, how can i say, not give as good a service as others.
In anticipation,
Thankyou very much

Gamma currently opens (Only 1 provider at a time)
Pink 16e
Canal Nl 19.2e
Bulsat 39e

All cards are sold liek that as they are not legal and encryptions change.
Easy to prog, can buy a cheap prog from satfooldeals or Alsat.
Also can buy gamma from both.

These cards have been open a while and could get stopped at any time.
You may need a cam for the tm to read the card, though it has been know to work ok in tm slots.
Cards are approx ?69
