I'd highly recomend.....

.......Squadron for delivering model kits quickly. I have never been disappointed by their service. Squardron always seems to have the kits I want, and although I'd like to support my local hobby shop it is hard to wait four weeks when I can have it in five days, without government needles.

Does anyone have simular good business with other on-line merchants?

I'd like to spread it around as much as possible.
