What are some more commonly used sizes for end mills? I plan to buy about 10-20 end mills and just would prefer the most common sizes.

This completely depends on what you plan on doing:

What materials are you working with?
Are you doing mostly 2D cutting, or 2.5D profiling?
What spindle are you using, and at what RPM?
How fine do you need the details in your cutting?

Working with 2D cutting in wood and plastic, on my other mill I use:

2-flute and 0-flute spiral up-cut end mills in the common sizes (1/32", 1/16", 1/8", 1/4", ... up to whatever size you spindle fits).
A facing or fly-cutter can be useful if you need to mill stock to thickness, but that depends on having a stiff, flat base to work from. I don't have one of these, but would like one.

Buy spares for the stuff you use frequently. It sucks to shelve a project while you wait for a replacement end mill after a boneheaded g-code moment.

For sources, I have used the kind this seller has in the past: http://stores.ebay.com/CARBIDE-PLUS?_trksid=p4340.l2563

If anyone is interested, I contact that seller about making a custom Shapeoko set of end mills. If we can get about 10 or more people interested, he would be willing to offer some discounts. If anyone is interested in doing this, we would need to work out what types of end mills to put in the set, and we can go from there.

I ordered five 1/8" 4 flute end mills (for $18.75, so $3.75 per end mill) to check out the quality, but for a Shapeoko set I would suggest a few different sizes, as well as maybe a ballnose and a v-groove cutter as well. That way we could have one kit that has all the end mills you would need to do a variety of first projects, for a reasonable amount of money, that would fit in the standard 1/8" collet in a dremel.

I would be in for a set like that, your suggestion for what to include sounds good to me too.

I have had very good luck with the tooling available from Enco (http://www.use-enco.com/) If you wait for the right "HOT DEALS" sale flyer, you can get them for 2-5$ each, which makes it easy to stock up on ones that will fit the 1/8" collet. I am trying out the 1/32" one as a PCB router - we will see how long it lasts... :-)
