I'm new to the arduino, currently an owner of the arduino duemilanove, and I've made my way through the "Getting Started" projects, and I'm looking forward to taking on bigger and better things.  However, I don't know where to start in terms of parts.  What are good things to pick up?  And, considering I'm a broke college student, where could I find the best deal?  The breadboard that came with my pack is miniscule (170 tie points, no power buses or the like) so I'm looking to pick up a new one.  I've looked through amazon originally, then found www.sparkfun.com, but I have yet to make any purchases.  I've briefly looked through the various starting projects listed on the Arduino website, but I feel like the parts lists get kind of random, and I want something I can pull from for random LED projects, etc.  It should be mentioned that this is my first experience with physical electronics.  I'm a freshman computer engineer and we have yet to start circuitry or anything of that nature, just E&M.  Where should I start?

Thanks!

If your not in a hurry, this place has great prices and selection . . .

Take a look at dipmicro.com also, they seem to have really low prices.
Get some LED, 220 ohm current limit resistors, maybe browse mpja.com for some interesting parts like matrix displays, get a sample driver or two from maxim-ic.com to control it.
Hard to suggest more without a more concrete project idea.
pololu.com has good prices too for breadboards

Thanks for the fast replies!  I'm working on browsing through both sites.

CrossRoads, I updated my profile, and I'm attending the University of Pittsburgh.  I can't really think of any concrete ideas to propose though.  Earlier today I was trying to modify the sample project in the "Getting Started" book that has you fade in an LED while holding a pushbutton, attempting to make it both fade out an LED while fading in a second, but I couldn't think of a way to get the programming to work.

I never looked at any of the getting started books, I graduated with BSEE 25 years ago and just jumped right into my project. Started with picking bits out of a serial data stream (5 bytes that repeated, 6 of the bits represented lights on/off info) and just kept expanding from there.  Has been fun.
Why not come up with an interesting clock idea? Stopwatch or something, see how long it really takes your girlfriend to get ready, or how long the washing machines in the dorm basement run.  Get some 7-segment displays, scroll a text message across them on your hat (BEAT PENN!).  Make a soothing 3D cube and mesmerize your friends with the soothing patterns of LEDs trailing after each other.
Have some fun with it.
