I've been pricing NCE Power Cab systems and I've noticed a very wide price range. $128.20 http://www.ebay.com/itm/NCE-524-025...983450?pt=Model_RR_Trains&hash=item5af21c159a $199.95 http://www.ncedcc.com/component/vir...lypage=flypage.tpl&product_id=3&category_id=1 If NCE's price is $199.95, is a price like $128.20 - new, factory sealed with 1 yr factory warrenty - too good to be true? Also, how many trains can Power Cab handle? - "2 or 3" - Why is the word "or" used? Why not just say "3?" How many locomotives can Power Cab handle - all running at the same time? I'm sure the answers will depend on how many amps each locomotive draws but give me "trypically..." answers.
