Thanks for all the responses. (However, I didn't get as much responses as I expected) Here is the summary:
Total responses Received: 05 (including one works for a Fortigate competitor and one for a reseller)
Comments varies from "very bad product" to "I'm impressed". Certain GUI problems were mentioned. Also mentioned that it was not capable of handling Dial-up traffic. Works fine as a managed firewall for an ISP. Operates fine in both transparent and routing/NAT modes
* The bottom Line: Acceptable product, watch-out for some GUI pit-falls.
We however, decided to go for it
