So I'm contemplating making the Dive into EZ Track

[Doneldon]

If you want to use sectional track EZTrack and the Kato track seem to be the best.  Use the nickel-silver Bachmann's track, however, not the steel track.  Sectional track, especially that which has roadbed attached can get pretty expensive, though.  You can sometimes get a good buy on ebay but you may not find anything other than the most popular pieces.

Flex track and quality turnouts are less expensive, go down just a little more slowly that EZTrack, and work very well.  Also, I find a little more satisfaction when I lay out my right-of-way myself.  Too, there will be fewer joints so you won't need as many track feeders which is a consideration only if you are doing DCC or a really huge layout.
