Accelerometers - What makes a good one?

I'm looking into getting some accelerometers put together in a fair quantity. I've got one that I think seems pretty good, LIS3LV02DL/DQ from ST Micro. The datasheets can be located here:

I'm just curious about what you guys think about these. From what I gather, the DL suffix is 8-bit triple axis, while the DQ suffix is 16-bit, triple axis. The 16-bit chip is about $5 more, but you get reeeally good resolution. I'm just throwing this out there to see if any of you guys would be interested in one. I want about 10 of these for myself, but getting them through sparkfun is about $44 each for the 16-bit DQ version, $20 for the 8-bit DL.

Just looking over the general costs, I think I can do the DL version for about $12, and the DQ for around $20. The chips themselves are pretty expensive... If I buy these in bulk for myself, and anyone else who wants them, I think those prices will be pretty accurate. These would be pre-assembled, so all you would have to do is maybe solder your wires or pin header on.

    Hello Philldapill,

    I wouldn't be uninterested in the accellerometers, but would first want to see a response to my Paypal payment re the Propboards.

    I sent that in a week ago.

    I would be interested in up to 2 DQ units.

    Thank you, Tom Perkins

    Arg, yeah, I'm sorry it's taken so long. I've had a couple screw ups with other people's orders and sent some stuff to one person that hadn't paid yet, and marked another person that had already paid as "sent", which somehow didn't get sent. Yours, along with a couple others, shipped Thursday so it should be there sometime mid next week for sure.

    Turning into a small company, Phil? Anyway, I'd like a couple of each.

    Not at this rate, SRLM... I'm going to have to get some actual software to keep track of everything. To be honest, I'm not a business man. I'm cheap. I like to buy big quantities of things so the cost comes down, and sell the stuff I don't use. Sometimes I make a couple bucks, but mostly, I end up just getting my stuff for free, well, minus the work on my part. Did you get your boards yet? I want to start crossing people off that have gotten theirs so that I can put this little venture to rest and start this new one.

    Phil, as Thomas Edison insisted (take note): "Get the money first."
