Hello, there are many kinds of TTs with various price tags so if you mention your budget for your TT, amp and speakers , members can tell you the right answers. However , TTs are of various kinds such as belt drive, idler, direct drive etc. You can either buy a new entry level TT with phono or you may choose preowned ones that are put on sale . You may find them on different online stores like hifimart or you can search for the TTs on our own forum. As regards vinyls there are many sources, since you are from kolkata you can go to the Wellington square(Lenin sarani) , choose your vinyls, bargain and grab. Hope this helps.
Cheers
