I was very lucky -- the Peco catalogue just showed up in my mailbox one day. One of my wife's penpals and her husband (a model rail) went to Pecorama and sent me a souvenir.
I'll answer any other Peco questions you have.
Don't know. They get a lot of flack on forums for it. It's consistent with the fact that their magazine Railway Modeller, until very recently, refused to print web addresses.
And they could do so much...
