The price depends on which markets you want to receive and market fees as well. It's impossible to give an estimate. Tell them what you require and they'll price your package. I used Tenfore a few years back without any problems.
This is the point of multiple layers. There's no need to pay for anything. I've got 5 protecting various areas plus antivirus and firewall, then 3 scanners. 2 cleaners and and a reg cleaner. Ain't much room to get through that lot. ;)
