Remember that while planning SIP, three things are required. The first one is your risk-taking capability, the second one is your target (for the specific purpose you want to invest) and the third one is your time-horizon. In absence of these three information, proper guidance can't be given.
So, I am assuming that your time-horizon is five years, and you have moderate risk-taking capability. Assuming these two factors, I would recommend you to invest Rs. 3000/- p.m. in a equity-oriented hybrid fund and another Rs. 3000/- p.m. in a debt-oriented hybrid fund for proper risk-balancing. If you maintain SIP for five years in these two categories of funds, you would additionally have Nil tax obligation for equity-oriented hybrid fund and you would get indexation benefit in respect of debt-oriented hybrid fund.
The best funds in these two categories can be easily obtained from various mutual fund websites like www.valueresearchonline.com or www.morningstar.in. (I do not mention the names of specific schemes on principle.)
Caution: Explosive. Handle with care.
