Cisco ASA 5505 is one option.
If you have access to an older pc with a couple of spare network cards, may I suggest a software based solution - smoothwall(www smoothwall.org).

It's easy to setup and manage, and is very good for a freebie.

I've tested it's security with grc and had no problems at all.
SonicWall and Aruba Networks both make a great product.

If you are looking for an inexpensive solution, you may want to look at getting a router that supports DD-WRT.  The DD-WRT firmware was originally designed to replace the firmware on the LinkSys WRT54 series of routers with something much more robust.  It has since been updated to include a variety of other makes/models of wireless router.  Check out the website at http://www.dd-wrt.com/site/index.  Be sure to check the router compatibility list before purchasing.

or look at FortiGate ... 50B or 60C ... nice boxes with lots of features, from basic firewall through IDS/IPS, Content-scanner to filter out malware and spam, security scanner, ... and very competitive pricing ...

ASA 5505 or SonicWALL TZ series for good bang for the buck. The SonicWALL is more end user friendly if that is a requirement for your choice. The TZ 200 is a good SOHO unit.


Thanks I appreciate all your help
