In TT there are two Internationally followed ways namely shake-hand and pen-hold grips. I suggest to opt shake-hand grip as it has greater flexibility while playing majority of shorts
In India one of the good TT bat manufacturers is GKI. For beginners there are two bats in Kung-fu series namely Kung-fu and Kung-fu deluxe. though both has same rubbers prefer deluxe as it has a handle with good grip.
