jackdaniels1,
For most people, something like the Fireboxes are really overkill. A basic "home" router will fit your needs unless you have specific needs outside of just protection while you're web browsing, sending email, etc.
For many people, I've gotten D-Link routers, b/c they are easy to setup/configure, and they work fine with no issues, really.
Also, my personal recommendation is that unless you want to get the absolute cheapest you can get ($15 to $20 typically, though you can occasionally find for a little less), is to get one with built-in Wireless, at least Wireless G, though I'd recommend Wireless N. The reason is that you may not need it now, but you can disable it, and then when/if you DO need or want it, you only have to enable it, rather than buying a different router.
I've installed a $15 or $20 router for a friend that I got off of NewEgg, and it was pretty straitforward. However, those wireless routers by D-Link which I got for others were easier to install. I just had to disable wireless for the one or two who did not have a laptop, for instance.
The DIR-615 is an ideal model, I think, for someone who just browses the web, sends/receives email, maybe does mild gaming online, and doesn't need the fastest performance - not gaming, file sharing, etc, but wants an easy to setup router that provides protection with just a couple clicks after install.
You can get the DIR-615 usually for around $40 or sometimes perhaps $30.
I personally own and use the DIR-655, and love it's performance, features, ease of setup, etc. I've installed it for a few people and recommended it for at least one personal friend as well.
Here's one link for the DIR-615:
Or $1 cheaper at Amazon:
Here's a listing of just wired routers at NewEgg, sorted by lowest price first. From what I'm seeing at this moment, I'd definitely recommend just getting a wireless router. Looks like the most you'll save right now is $5 or $10 to go wired... and you can probably find other wireless routers for less than the D-LINK.
If you prefer other brands, I've seen these work okay:
NetGear, Linksys (usually overpriced), US Robotics, D-Link of course, and probably a couple others I can't remember, but that sums up about the top of the line for "home" routers.
The one brand I would currently recommend against, based on actualy setup nightmares would be Buffalo. But that was just with one router. The cable company had sent out 2 or 3 different technicians (which doesn't say much by itself, sadly) to set up a friend's wireless router (Buffalo) for them. It was a headache, but I did get the thing working. Based on my experience there, I'd not recommend it, and I certainly wouldn't buy one myself.
Hopefully that'll give you some info, and hopefully not TOO much info.
