Fountain

http://fountaintype.com

The Fountain foundry is a great site because many of the typefaces are shown all at once. This makes it easier for me to see what I do and don't like. Also, there is more than just regular type. There are typefaces that are very graphic, such as cartoons or other forms of illustration.

Misprinted Type

http://www.misprintedtype.com

Misprinted Type is a site by one of my favorite designers, Eduardo Recife. His typefaces are all handmade and this is why it is such a great foundry. None of the faces are the usual ones found at most foundries you look at, but are original. The site is also extremely easy to use because everything is found in the top left corner.

This type foundry is great because you can sample different typefaces and allows you to create a custom typeface. On the left side of the type page, there are sections where you can browse by styles, collections, or by just what's hot. This site is very easy to navigate through, which is good because I don't like to waste my time.
