When I decided to go to 1/350 I bought a Revel Mo to get used to the scale since it was so much different than normal for me and it wasn't nearly as big as investment, actually only $10, so if I mess up it's not a huge thing.  But I have mostly Trumpter and a few Dragon escorts.  The Dragon kits are way more detailed but that's not that big a thing when they both are so good compared to the Revel. 

Hope that helps.
