I had a quick Q and would really appreciate if someone can please help me here. I have read a lot of articles on this forum already but I am not able to understand or take a final call. Here are my Q's, any experienced revert will really help me a lot ! Thank you in advance !

1. Local Gunsmith says that 2001 IOF Mark 1 will cost 1.35 L, reason, this is a solid and hard piece and better than what quality you get today or from the new IOF's if you purchase today.
2. New IOF Mark 3, Mark 3 Light or Mark 4 - which one is a good buy for a beginner ?
3. Should I get into the hassles of getting a TL from Delhi and then going to the Factory to buy it, is it worth the time and investment, or should I simply buy a Mark 1 for 1.35L ?
4. Please suggest if anyone would want to sell me a Mark 3 or Mark 3 Light which is reasonably old like maybe 6-9 years maximum, what would be the cost for it ?
5. I am talking about Delhi and not other states. Sorry !
Looking forward to hearing from the experts soon ! Thank you very much in advance ! Thanks.
Best Regards,
