I have 8 or 10 of those & one of mine has warped trucks that I've got to fix someday.
Mine are SD70's, 75I's & 75M's. Nice loco's, but, I haven't paid more than 50 or 60 bucks for mine brand new.
how did you pay those prices for them brand new? I've been trying to find a few on ebay and they end up going for full retail used.
