You want an American Carrom board then. Indian Carroms has small pockets and a large striker. American Carrom boards are made by the Carrom company and you just get the same one everyone has:
Now you can get rid of the rings and buy a set of real carroms, but then you will have to dust your board with cornstartch/carrom powder for almost every play. The only other option is a custom built board. The Hilinski brothers will build you one, but it will be expensive. Ive thought about building one myself, since more people will play American Carroms due to the ease of scoring, but Ive never had luck with Carabana wax.
My Indian Carrom board is not the best, but it is a Synco Tournament made out of 14mm Indian Ply over Birch. It plays identical to board twice the price, but does not look as cool. It still cost me about $300 a couple years ago. The best place to get an Indian board is from

I also highly suggest Crokinole, if you want another good dexterity game (its the backside of the American Carrom board with the pegs), or Pitchcar if you want a fun project.
