Hi, I have a couple of duplicate Alternators and it happens to be of both type of packaging. I plan to open one and keep the other MISB. Is there any tendency in term of rareness for Bubble/Dome or the Red/Blue packaging? If so, I'll keep that one MISB and open the other. On a different note, I know Alt. Track was in demand at one point but has he dropped in popularity? I'm offered MISB Alternators Tracks (Red Packaging) for $15, shipping included. That is quite a price drop. I'm thinking of getting it because that is a sweet price.
