Hi Lou;
Like you, I live in a rural area with one hobby shop that caters mostly to RC, so most of my purchases are online. Haven't ordered from Lucky Model or Hobby Link, although their prices and selection look good. For most kits and Testors and Tamiya paints, Scalehobbiest is hard to beat on price, and they offer good shipping rates and times. Sprue Brothers are a little faster, and have a much broader inventory, especially aftermarket and non-mainstream kits, but expect to pay a little more. Squadron is the pricier of the three I have ordered from, but they carry a huge selection of products and their monthly flyer has some great deals. They are also known for "surprise" sales events, and their Black Friday sales are worth the wait.
