Yeah, the Bandai is cheaper, but ya gets what ya pays for - a toy compared to the Tamiya.
Like comparing the Lindberg M46 with a DML M46; there is no comparison.
Save for the Tamiya, you be so much happier with your expenditure.
AFAIK, the Tam Tiger I is an "early", so either Panzer Gray with whitewash, or Armor Yellow with whitewash would be OK.
