Need Wireless ADSL Router/Modem with USB (for pendrive, network printer etc.)

I am using BSNL Broadband. My NSN C2110 hangs quite often. After some research I found that D-Link DSL-2750U is a good model offering USB although transfer speed is limited to 2.5 MB/s. Its average online price is 2.5k. Letsbuy is selling at Rs 2349. Can anyone help me find it at a lower price. Present users of this device are requested to provide a review.

Also please let me know if there are any other good wireless modems with USB port within this price range.
