Which label should I go for?

Hi, currently I'm on a hunt for Manthrakodi sarees in Kerala. I don't want to spend a ridiculous amount of money on a single saree. I am thinking about buying a Banarasi silk saree instead to use as my Manthrakodi. Or is there any other material that I can buy? So my questions are: 1.Should I go for Banarasi saree? 2. Which shops would you suggest with a good collection at standard rates? I would like to keep my budget less than 30k
