I know http://www.3dprintronics.com/ is a reputable 3d printing store in India offering both kits and fully assembled printers. I would also check ebay as I have seen many printers and kits on there from India. I hope this helps.
www.3dprintronics.com - These guys are amazing. They have every thing you need for 3d printing. Great customer support and they know a lot about DIY 3d printing. I got a Prusa i3 kit from them. Everything is as it should be.
