First off, let me be the first to welcome you to the best modeling forum out there, I have been a member to a few, one ridiculed me for not reading the FAQ before asking a question, and one I dont even post or search on.
Second, all you can do is google model kits to find stores. Myself I ge most of my kits from other members here, or eBay. But if you don't like that route try www.emodelcars.com the sellers are mostly if not all members from this board.
Try these other sites if you want:
http://www.tamiyausa.com
http://www.testors.com
http://www.modelroundup.com/
http://www.hiroboy.com/catalog/
http://www.towerhobbies.com/plastic/listin..._car_model.html
Thats just to name a few that I have saved.
All those sites havve a tools section if I am not mistaken. But, it would be in your best interest to compare prices. I was looking for a paint stand and the guys turned me toward the Tamiya Paint stand.
Tamiya's price including shipping $29.00
Towerhobbies.com $30.18
hobbylinc.com $24.98
Hope this helps, if you have any questions please feel free to ask. It may take a day or so but someone will answer you.
