Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

And two of these motors: http://www.pololu.com/catalog/product/1102So what kind of motor controller would be best to run with these components?
So what kind of motor controller would be best to run with these components?
12V 5A stall? If you need bidirectional operation and possibly speed control (though ATMega328 you are using has hardware PWM anyway), this is going to be tough to drive with a single cheap IC (the common options - FAN8082, TA7291P, BA6956AN, BA6287F and TA7267BP - are all rated lower). There are several 5A+ full H-bridge drivers, e.g. TLE5206, but they are not exactly cheap ($7+). You might be better with two pairs of discrete, complementary power MOSFETs (e.g., NTD2955 + NTD4858N) to be honest...

Pretty much every link or picture that Soeren has posted in the past few weeks won't come through. Tried it from work as well, no dice. been meaning to send him a message. Soeren, i think that domain is blocked by some ISPs here in the states, or there's a broken router in-between.

Are they just drivers or controllers? Or neither?
Im not sure if im willing to spend $60 on a component like this... would it really be too hard to build an H-Bridge to run this?
Are there any drawbacks from using a simple homemade h bridge vs a motor controller?
Any other suggestions on where to buy or a search engine that will lead me to a place where I can buy are apreciated!

How do you know all these products? I'd like to be able to know about them and not have to ask everytime i need something!
