Do I really need a SONICWALL TZ 170?

[NCC74656]

The credit card software will use both broadband and dial up to get credit card authorization. No email or web surfing will be conducted with this pc. We are currently using a Linksys router and the software installer said that the router is hackable.

Anyone here have any experienced with a SONICWALL TZ 170 firewall appliance?

Anyone here using a linksys router suffered from hacker's attacks?

Any info is appreciated.
