I am buying second hand WatchGuard Firebox Soho 6 from ebay and at home I have apache and oracle server running.

The reason I am going to buy WatchGuard Firebox Soho 6 is to secure my home server.

Now the question is ...is it worth it to buy WatchGuard Firebox Soho 6? or should I buy sonicwall (secondhand )from ebay?
