Have you considered the Sirui? They appear to offer an Aluminium version for about 4k INR and a carbon fibre version for about 8K INR (without any head of course).

May I ask why do you feel the need to get a monopod?
I ask because I too wanted to get a monopod some time back (the 1100D+batterygrip+400 5.6 felt really heavy in the beginning). I have a Manfrotto tripod (with a pan head) so thought I'd try and use that in the field and see if that makes things easier.
It did make certain things easier (you can rest the camera on it if you're waiting for some action to happen, video quality is infinitely better compared to hand holding). But if you're on the tripod and the action is happening in an awkward angle then you have to unmount the camera and take the shot - this delay can result in missed shots. Not to mention wild critters don't like sudden movements.

So, in the end I dropped the idea altogether. Adjusting the height, mounting/unmounting the camera, changing the angle, etc frequently would've made things difficult.
Although a ball head may make things easier in this particular use case, but the other "problems" would still exist.
So, depending on your shooting style avoiding a monopod may be better.
