Any good sites for Tomy/Trackmaster Classic track/locos?

Hi the people of Blue Plastic Tracks, this is my first upload on here.  I've been scrolling Amazon and Ebay to look for Tomy/Plarail/TM1 stuff, and I saw either things that are way too expensive, or things that I wasn't interested in.  Any sites(or search settings for Amazon/Ebay)would you consider as a good site for buying locos or track from?(I'm not interested in TM2, btw).  Thanks
