What do you use to research MFs

#1
Hi,
I have being using Moneycontrol for some while now to look at the past performance and other details of MFs. But for a last few days I also started looking at valueresearch and I found that there is lot of difference in some return figures. I also don't want to beleive in the numbers provided by sites which have big AMCs as their main sponsors. The only trusted site that I see is AMFI but there are no tools to analyze the data on AMFI site(like sort in order of returs/AUM, fund performance vs Sensex etc). What tools/websites do you guys use for your research.
