@Biker,
Another broker you should consider is
ProStocks. They are the discount brokers with few keys features you are looking for:
1. Zero Account Opening Fee
2. Lifetime free AMC Demat Account with Rs 1000 refundable deposit.
3. Two trading plans to choose from:
a. Rs 15 per trader across segment
b. Rs 899 unlimited monthly equity trading
There lifetime demat account is good to apply in IPO's on family members name and HUF as it increases your chance of allotment and its Zero AMC Demat.
