where to buy details?

http://www.aefdesigns.com for accesories
http://www.greatmodels.com you can find some things
http://www.squadron.com " " " " " "" "" " " " " " " " "" "
those are just a few places I like to hunt for goodies.
you can also check with the manufactures of kits, or just go to the local shop and sink some cash and see the goodies in person.

http://www.rollmodels.com/
http://tigermodels.com/

are a few more. You could always try a google search too.

Here are a couple of more places to look:

www.missionmodels.com
www.modelmecca.com

and Ebay is also a good place to look for stuff.

One of the best IMO, they have everything from ModelKasten to MIG...have to check it out. very nice people to boot..
