Query: Great Linux-powered router with USB storage

As soon as I received my Linksys WRTSL54GS, I flashed it with the OpenWRT firmware... and my device works great. It's been running for 3 wks now since I've bought it, with no problems. I did not attempt to use Linksys' OEM firmware, which other reviewers have noted is not very good.I am irked that it is much more expensive than the Linksys WRT54GL, but the extra RAM, flash memory (useful for OpenWRT), and USB port were worth it for me. You're not going to break any speed records with the device's 266 MHz processor, but the ability to access disks over a network without the need of another full-blown computer is extremely convenient.It has only one antenna, but most real-world tests show that two antennas are not necessarily better, The antenna is unfortunately non-removable, unlike the WRT54GL, so you cannot easily replace it with another.All in all a great, more versatile WRT54GL alternative.
