For some reason, turntables have a huge mark up in India. Pro-ject/ Rega are absurdly priced. If possible try to buy abroad and hand carry. I have done the same with the table and may dozens of LPs.
Go for either Project Debu Carbon DC or Denon DP300f. Don't opt for Regas, for upgradation you will always have to stick to Rega accessories.
What existing components do you have? If your existing gear is entry level, a Rega RP1 or Project Debut (RP1 is better than Debut) or the Marantz 5005 is good enough. It is true you might need to stick with Rega accessories if you bought RP1, but once you have graduated from your existing setup, you have a lot more components to worry about for an upgrade than just a cartridge or a phono-stage for your TT.
Thats the rest of the system especially the cartridge and Phonostage ? Also what kind of LPs do you have ie newer releases or the older ones ?
Offtopic, but did you upgrade your stylus to Ortofon Blue 2M ?You have a good set up. But be sure whether your amplifier has inbuilt phono or not. If it has a phono input then you can hook up any TT sans phono of its own . If your TT has inbuilt phono then you can connect it to your amplifier even if it doesn't have a dedicated phono.
you will need a TT + Phono and ideally, for your budget with one built in so do take care of that .My existing setup is a Pioneer HM86 network streamer and amplifier + a pair of Dali Zenzor 1 bookshelves. It is quite basic.
Love listening to classic rock.
