"Good...after you update it"4.0 starson by mrosenecker
Pros: USB Printer Support, speed, ability to run 3rd party firmware. Once the 3002 firmware was installed, the whole thing worked great.
Cons: Shipping firmware is horrible. The Asus website for firmware downloads was very frequently overloaded (or buggy). Printing more than one page on original firmware crashed the router repeatedly, requiring me to pull the power cord.
Summary: Bottom line...the router was buggy, required reboots for the littlest things, and crashed several times when printing a single 9-page PDF file (requiring me to pull the power plug). Once I upgraded to the Asus 3002 firmware, it started working great. The web interface is much improved from the earlier version, and the USB printing started working perfectly.
I haven't tried the DD-WRT 3rd party firmware, and probably won't, as long as the 3002 firmware works out OK for me. It's nice to know that I can install it, should the need arise.
Got it for $25 ($45 - $20 rebate) on another site...
