you can get one for about 500-1000 rupees......i have a tiny korg one thats more than enough. But if its for home use you can just use a virtual metronome from your computer or if u have a processor then that.....but if u still want one for ur gear you could get a korg one for about 1000 rupees or maybe even better for cheaper
If you have a personal computer with internet connection at home you can download free softwares which can be used as metronome. Its definitely money-saving.
i bought a korg metronome for 1200Rs. now you can get it for 1000. ibanez metronome has a tuner so it is better than korg one. ibanez metronome is also in same price range.
