Need a B/W Laserjet Printer with Automatic Duplex

Hi Friends. I need to buy a Laserjet Printer that has a good PPM and is able to print on both sides of the page automatically. I need to buy it for a small business purpose. The cost range is around 12K. Can you please suggest some nice printer.

We already have a deskjet but the running cost is quite high. So it is required only for basic and efficient printing.

I looked for HP 2015D and 2055D Laserjets but they cost around 24K, that is almost twice as high the cost.

Can you please suggest in other brands as well?
