Is there a thread where I can see a quick photo of various members track with there ballast & paint brand of choice so I can decide which I like best ? And if not, why not ??
The obvious answer to this is "because neither you or anyone else has started such a thread"

You could try asking in the relevant section (Track, Points & Underlay) and see how many replies you get, or you could try looking through the layout threads where a lot of people have probably already stated what they used, or if they haven't you could ask them if you like the look of a particular picture
