Appropriate Hardware Firewall

[Hedge]

I own 5 web servers in a solo facility and I am looking into the idea of putting my own firewall in place for just my servers. I have been looking at Hotbrick, SonicWall, and Fortigate solutions. The problem is I am not sure which one will fill my needs. I don't want to spend more money than I have to obviously. I would like to spend no more than $2500ish if possible. Our network traffic is on average 7 - 10 mbps and as I said I have 5 servers but will slowly add more. I mostly want to be able to block certain IPs and ports etc. any model number suggestions etc would be helpful

Watchguard Firefox X550e ($1000-$1500)

Cisco ASA 5505 ($500-$800)(might need to upgrade to a 5510 if your going to have more then 10,000 concurrent connections, the 5510 is about $2500-$3000)

I have not used any sonicwall products but you mentioned it, reading a bit the soincwall pro 2040 looks pretty decent (~$1500)
