Wanted Elise series 2 ECU

[eos]

I am currently on the lookout for an ECU for my Rover engined Series 2 Elise, and would be grateful if anyone
has any info or knowledge where I may source one ( apart from the silly price of a main dealer ).
I have been told it needs to be a series 2 Rover engined part as apparently the 111s etc are different.
Any help much appreciated.
