If you like Ubiquiti you could look at their Edgerouter Lite. I'm real happy with mine. $100 and it'll outperform monowall and pfsense on way more expensive hardware. With a basic NAT setup, plus SPI firewall (the basic "permit established and related, drop others" rules) I've measured it at over 500mbps throughput. It probably would do faster, it's CPU wasn't fully loaded, that is just as fast a test server as I could easily get to.
Now of course it is more on the routing, less on the firewall n' such so if you need powerful firewall config, it isn't as much your thing (and won't get as good performance). If you load it down with too much stuff it'll slow way down, particularly since part of its speed is derived from hardware acceleration on its chip, so if tons of stuff is hitting the software it won't be as fast.
Just another option to look at.
In terms of the realtek chips, ya it sucks but it is what you get for the price. Intel NICs are expensive, because Intel knows they are worth it. They charge more for their chips than other vendors by a good bit, so you don't see them in cheap solutions.
