Need some suggestions about the method i need to follow to import an airgun at my door step considering the total money spent in the whole process. I understand that this question may have been asked a bazillion times (lol) ...but please bear with me.

I still dont have a gun club membership (but will have to go for it)
I have gone thru many forums, discussions about importing an air gun.
I am not looking for match quality, just for back yard plinking fun and am a fan of beretta 92fs / Taurus P92 styled pistols.
Hence i am looking for a Swiss arms P92 CO2 0.177 cal full metal blowback air pistol.
Saw some websites, called up a few online dealers here in India, and the price range difference is freaking huge leading me to doubt that there is something wrong somewhere.
Option 1 : I approached airsoftgunIndia.com guy called Pankaj Kapoor who quoted Rs 30k (no membership needed)
Option 2: I approached relish sports guy called Ali who quoted Rs 23K (membership needed)
Membership for a year here in Pune costing me Rs 10K....so effectively i end up paying for gun + membership= Rs 33k
Option 3: Now i visited Pyramid air wesite where this same gun which i want is listed for $100 Plus priority shipping $80 total $180 = Rs 12k approx...so total of gun + membership = Rs 22k
So will this attract import duties and taxes? i read somewhere 35% of gun cost and shipping ? is this true? for a BB gun costing not more than $100? i read somewhere no import duties for air guns of 0.177 cal and less than $200.
Are there any other hidden costs not known to me while importing a bb air/co2 pistol from pyramid air.
Which option should i follow to bring home my requirement? at lowest cost...i dont want to pay unnecesary money to someone.
Option 1 & 2 seems to be simplest but also seems i am throwing away extra money which i can use to buy addition bb ammo and co2 cartridges.
Option 3 seems feasible but its totally not know to me as i am a first timer in this experience.
Please point me to the right direction.
