I have an opportunity to get a new one for 350$ and I wanted to ask you guys opinions on it. Any problems?

 

Could you kindly double check to see if the unit is suitable for coils with inbuilt igniter? Last time I looked at this unit it's only good for ignition system with separate coild and igniter. If this is still the case then it's not suitable for the s2k.
I've seen the unit on 2 skylines and they both works very well. Sparks and twin spark is greatly improved.

Much appreciate for your feedback and progress on this unit regardless of the result.
