Afternarket tracks and barrel

I’m looking to build a Tamiya 1/35 Tiger I and I would like to use aftermarket metal tracks and an aluminum barrel. Does anyone know of any good websites to mailorder these parts from.MartyM2828.

A few good ones are:

www.hometown-hobbies.com
www.greatmodels.com
http://www.airconnection.on.ca/
www.modelpoint.us

For the tracks, Fruilmodel is the only option if you want metal tracks. There are a lot of options for the barrel, though. Personally the multi-piece Aber barrel is my favorite. 13 pieces with PE, all metal and beautiful. I picked mine up at airconnection

Where are you? Try http://www.squadron.com/Index.htm for the USA or http://www.hannants.co.uk/ for UK/Europe

I live in USA. Thanks everyone for the help.
