Ho scale Brass CB&Q O-5 question

[arnold299@a...]

Hi listers,
I am trying to decide which brass CB&Q steam locomotive will be my first.
I am currently looking at O-5's. How do Overland Models, Oriental and 
Challenger O-5's compare. I recently waited too long to purchase a Overland 
O-5 posted here earlier because I knew little about this locomotive. Since 
then I have determined it's a pretty smooth runner. So how does the Oriental 
and Challenger models compare and are there any others I should look at?

Thank you,
Scott Arnold
