If you want to get these parts cheap with 2 week shipping, go with Tayda Electronics. If you want to get these fast, try Digikey. Female pin headers (same number of pins at your socket) OR more male pin headers if you want it to plug into a breadboard.Male pin headers, 2 sets of 5 (if your programmer has a 6 pin cable, go for 2 sets of 3.A chip socket (pick one that'll accommodate the chip you plan on using).In addition to a chip, you'll want a few parts to make a cradle otherwise, you'll have to breadboard out all of the connections whenever you want to program anything. Take your pick any of these will work well. You'll have to edit a few things if you want to use it without its crystal. The Atmega328 is the chip used on the actual Arduino.The Attiny2313 is a 20 pin chip with 2kb of memory.The Attiny84 and Attiny44 are 14 pin clones of the chips above.The Attiny85 and Attiny45 are tiny 8 pin chips with 6 functional inputs and outputs with a max of 8kb of memory.Most AVR microcontrollers will work with the programmers I listed on the previous step, but only some can be used with the Arduino language. Unless you plan on programming air, you might want to get a microcontroller and some parts for a programming cradle. Once again, make sure you get one with all three jumpers mine looks nice and comes with a fancy case, but is missing 2 of them. Due to my aforementioned lack of money, my programmer was a USBasp. The only difference between the two is that the 10 pin connector has 4 redundant/unused pins. Your programmer might come with either a 10 pin connector or a 6 pin connector. It is without a doubt the most powerful of these programmers and can be used with AVR Studio (complete with debugger!), but costs around $35 to get. The AVRISP mk.II is Atmel's official programmer for the AVR line of chips.Keep in mind that it cannot program certain high end Atmega devices due to memory limitations. It costs $22 from Ladyada, but knockoffs can be had from eBay for around $12. The USBTinyISP is a step up from the USBasp.It, obviously, will only work on computers with a parallel port. A parallel port programmer is around the same price and can even be made at home.Be wary of the shipping times that the Chinese ones come with. You can find them on eBay starting at only $3. Make sure that your model has three jumpers (or three pairs of holes with J1, J2, and J3 printed next to them). The USBasp is quite possibly the cheapest programmer out there, but you should be careful when buying them some versions use outdated firmware or are missing jumpers.There's a large number to choose from, so I'll give you a rundown of the most popular ones.
