Was browsing broadbandgear site and stumbled across this deal on the front page.
You get a free Wireless adapter (valued at $29.95) when you purchase the OPEN Networks 824RLW modem/router.
The OPEN824RLW is just a rebadged Billion 7404VGP-M so it is a top notch modem router with VoIP.

This offer has been running for quite some time now, and it's most likely permanent. I wouldn't say it's really a bargain.
Also, I bought this router from one item a day site for around $90 ($100 inc shipping), so it's not the lowest price you could get.
