Well I've almost given up on someone releasing a model of a BN GP9 in HO. I have been trying to find a undec. Proto 2000 engine with no luck ( for less then $125!). So I've narrowed it down to 2 choices. 1. Buy a GP9 off eBay decorated for a less common and not in demand roadname and repaint it. I have seen several go for less then $50. My question is how easy is it to repaint an engine thats already decorated? What is a good way to strip the paint or can you just paint right over the old stuff? 2. Buy a old Front Range shell for a GP9 and power it. These Ive seen for less the $25. How good were these models and what is the best way to power them? Id like to use a Proto 2000 power unit, there are 3 on eBay right now for $12.
