pulled this out of that ipaq (and sold the parts from it for a killing on ebay  )
i wouldnt mind getting a couple more of these, with intact solder balls.. i basically ripped it off of the motherboard, so the underside looks pretty brutal :/ |

You need to remove chips more professionally. Just having a chip is one thing, but making sure it is usable and works adds value to it. If the buyer is sure that it goes then that makes it a better sale and will improve the value of your collection if you retain it.
Sheer metal is one thing, but what is better is guarantees of usability (not that anyone is going to use it) but it is even better.
Take for example stamp collectors, they go to great lengths to ensure that glues or water stains do not stain their stamps.
We could take a note from them. Ensure that our chips look as original as possible so as to ensure they have the highest possible value. |

Bah, I don't think that anyone will try to resolder and reuse BGA chips in our collector's community 
I use a heat pistol (I hope that you understand what I mean) to remove my BGA chips, it takes around 30 seconds. |

i try to keep all of my chips in the best condition possible. ive spent 2-3 hours on one chip trying to remove stickers and crap from it without scratching the chip itself  .. also, straightening pins.
soldered chips are a pain in the ass though which is why i dont bother with them much. the ipaq i took that off of was dead and i didnt care to have the entire motherboard taking up space for such a small chip. its only my second bga chip though so im not too good at unsoldering them
minuteman, what do you mean by heat gun? |
