Well, I know this belongs in a "general hardware" topic, but I couldn't find one...
What would a good transistor for running 2 amps at 5 volts? Preferrably rated at a little more than that, just in case. I would also prefer them on ebay, and I need 28, so hopefully not more than a buck a pop. Also, I need them to be NPN transistors.
Please respond if you know any good alternatives.
Thanks,
Jeremy
Must it be a NPN rather then a high current logic level N-channel MOSFET?
By the way those wanting to do high side switching with P-channel MOSFET usually don't find them quite as common as their N-channel brothers, at least with good low Ron specs. Here are some I ordered on E-bay to check out.

Well, I really just need some transistor that when I put +5 (through a 1k) to the Base, it will pass through the ground, or +5 at 2 amps. I don't know much about transistors, which is why I ask for help. The ones you posted look a tad excessive, but if they're good, I'll get em.
Or you can just go to Digi-Key and get a 4A 400V NPN transistor for $0.23 each:

Love you 
Do those transistors require a heatsink with them tho? Cause I don't think that will be cheap if it does 
Oh, and on a side topic, if your the creator of RC, then I would like to tell you that your designs are amazing.
Can't take the credit, but I'll take the compliment XD

Use power MOSFETs. It's easy to find some that will not even get warm switching 2A at 5V.
Well, due to a day of thinking, I found a way to use less transistors. Thanks for the suggestions anyways guys
