Decided against converting the S2000 to a coil pack, so want to go for the 710 but I'm looking out for second hand/cheap units as it is very expensive!

ms3 will do fully sequential coil on plug and they are in the process of developing variable rate cam advance (already has fixed rate cam advance)

How much are they?

Also are there any disadvantages to it compared to the better known brands?

yeah nobody (hardly) maps them (ms3) on rolling road and with all the tech on an s2000 I wouldn't trust myself to wing it.

I'm using a supercharged volvo t5 5 cul and I just bit my l lip and started saving for a 710. it'll be the most expensive part of the car by far but worth it I think
