ok, so im debating whether to get a propstick or a development board for the prop, my last board got wore out from desoldering and soldering stuff to it so im looking to get another one, but a board with the usb already on it. any ideas on which would be better for a college kid with no soldering stuff around...also any tips on which one would be best to get would be good. i have asked other people but they are "poor college kids"(im sick of hearing that) so any input would be good.
and the reason this is in the sandbox,
i am looking to build a board that will have the prop an mp3 decoder, sd card, audio out, and ethernet connections. i have to many ideas that i want to do and keep alive without cannabalising my current project. so what i thought i would do is get a double sided protoboard and mount all the hardware to it. leaving the sd card, audio out, ethernet out, and usb to face a certain way. then this would all be built and in order to get it to switch between current projects it would clip into a socket and then have the code analyze which socket the board is in and then switch around i/o's accordingly. my question is do they make sockets that can clip onto the edge of a double sided protoboard or am i better off soldering on a row of headers. (sorry if this all sounds confusing)

The Propstick also has an on board voltage regulator, USB interface, and 32KB eeprom. as well.
The Propmod requires a prop plug for programming and a regulated 3.3V input but has a larger 64KB eeprom.
Since they are intended to connect to another board having a regulator on board may not be an advantage for the Propstick, while the on board USB interface would be. The Propmod has the advantage of a larger eeprom and also has sturdier pins, which makes it more durable if it is removed and inserted frequently.
I have a protoboard, and have soldered four sets of 2x8 pins around the prop such that the even pins have the output pins connected (2, 4, 6, 8, 10 12, 14, 16 have P0 - P7, P8 - P15, etc.) while pins 1 & 3 have +3.3V, pins 5, 7, 9, 11 are Vss, and 13 & 15 are +5V. I use a short ribbon cable to connect to the board I am working on. I find this works very well for me.
You should also take a look at the Gadget Gangster Propeller Platform board. The boards are designed to be stacked by plugging in one above the other somewhat like the Arduino shield boards.
