Monster 600 faulty CDI's - whats my options?

recently bought a 1997 600 Monster as a winter project. Before I strip it down I thought I would get it running, which is proving difficult!

It starts, sounds OK, but runs quite rough... and soon as I try to rev it it cuts out! I have done all the usual checks and come to the conclusion that its the CDI units. I know its strange to have two faulty ones, but I dont know the history of the bike, and they may have both been swapped. the bike is stuck on full advance when I check it with the strobe, and seems to advance more as the revs rise...

So what are my options? seems new ones are £500 ish a pair... is there an alternative?
