I would go with an MTH set. Engines already have Proto 2/3 operating system. No operating modules required. You can also download other sounds, etc from the internet. As you become more addicted to O gauge, you can expand to include other manufactures locos. I, personally would highly recommend buying MTH Z-4000 transformer as it is a long-term invstment and has a great reliability record. To the Forumite who had an issue with early MTH, take another look. MTH has high quality7, a vast arrya of products, better technology , consistant focus and management.
I know it sounds like I'm a MTH fan,,,,which I am! Dave G.
