The 206 was a much better than the CD63KI Sig and the 200 was a far better transport than the 206.
The early 200, the with serial numbers 1xxxxx used the Philips CDM4/21 which is a mess to get hold of these days. Later units 2xxxxx used the CDM4/19 which is very comon and you can pick them up all over the place. probably more CDM4/19's on the plannet than any other mech

Even with hard to find laser units like on the 4/21 it's normally the motor that is causing the trouble and then you can use a cdm4/19 motor.
