You can build a small simple router for probably a good amount under $1000. Maybe under $800. But it depends on what it's like getting parts where you are. India's a big country so maybe you can find all you need locally, hence it'll be cheaper.
You said its for 'home', but what will it be used for...wood/metal?
What size do you need it to be? 10 ft long by 10 ft wide, or 3ft long by 2 ft wide....
If you just want a starter type,you can get away for a lot less money than that..I tossed together a MDF critter a while back, pretty cheaply,
a half sheet of 3/4 mdf, cabinet drawer slides [maybe $40], 1/4 threaded rod, real cheap driver kits [maybe $16 each?], battery charger power supply, and surplus copier steppers..
yeah, it's ugly and doesn't have great performance, not to mention backlash.. but it does go back and forth...
