3. Do you really think sd2snes making cost is 200$? is much much less
Counter question: Do you want to work for free? If you think the manufacturing cost is all that makes up the price you are beyond naive.
Basically, all quality and cost factors aside:
1. you want to fuck me over (and krikzz): buy Chinese. Can't exactly blame you as far as I am concerned. But don't expect any more support or answered questions.
2. you don't want to fuck us over: buy from krikzz. 
And thats what the problem is today Ikari,people expect everything cheap or even worse:FREE.
Now i don't have a problem to pay 200$ for a device thats giving me so much fun for in the place.
And there are so many games on snes that arent cheap,so why there is a problem for the price,i don't understand that.
There is a super everdrive for people that have enough with that and only can or want afford that,and sd2snes where you can play much more and willing to pay for.
I'm happy with my sd2snes ikari,it works perfekt and get support that's increases the games you can play on.
I say thank you,and btw,super fx works nice on it.
