I think the point to realise here is, like everything else in this hobby, there is no right answer to 'which is best' etc.

The Dragon Firecrypt CAM is probably the most powerful and has some of the best support etc, but the Matrix or Matrix Reloaded might do the same job, whilst saving you a lot of money. Does that make it better? I don't know.

My only piece of advice to you would be this. Spend as little money as possible on CAMs and cards, and don't get caught up in buying the latest expensive plastic every five minutes. There is a lot of money being made from the punters ATM. Just get something that works. Spend your money on either a good card programmer (Infinity Unlimited USB etc.) and/or a good CAM programmer/method.

What works today will not work tomorrow. That's the only true take-away.
