Who's attacking you?
You said, "The WatchGuard X500 is the minimum I would start a SOHO business out on, at least one that I wanted to feel as though I protected them. The X700 is my normal starting point for any business of other type, meaning larger than a home based business."
When I think SOHO, I think of a broad range of businesses, not just computer based.
While it's now clear that you were referring to more elaborate SOHOs (Residential users don't normally have more than 1 Public IP, so the Netgear Part #FVL328 would be a perfect Home User firewall.), your initial statement was challenged.
For someone who frequently picks fights, you've sure got a short fuse.
