Hmm. Their prices look very competitive!! 2GB for 1500 a year. I have never given or taken hosting at such low prices.
Ask them a few pre-sales questions. For example:
1. Do they offer cPanel, if not whats their control panel? Can they give a demo?
2. What if you want more email addresses or databases?
3. Whats the config of their servers and where are they located?
4. Do they give any free trial period?
etc.
Think of things that you want to know and ask. BTW, IMO these rates seem too low to me. And in hosting we usually follow one rule

I have mentioned this at many threads now

If something is too good to be true, then probably its not true. So take your time, ask questions and then decide.
As for Digit's fast-track, I really wouldn't read too much into the statement that all Indian hosting companies are bad! Thats simply a myth.
