You not been on the 1098 forum ?
There are some good vendors on there and usually some Akra systems etc.
Remember that you will need a DP race ecu or a Nemesis or you will get error codes if you fit a full system.
Value for money wise you cannot go past the Termi. If you bought the full system you would get a replacement ecu that is set up correctly for the system AND will still allow the traction control to work.
