Accelerometer - help please

I’m looking for an accelerometer.
It must:
[ul]
[li]have 3 Degrees of Freedom/axis[/li][li]Be sensitive in the +/- .25 g range[/li][li](doesn’t need to measure outside that range at all)[/li][li]be less than an inch in at least two out of three dimensions, less than three in the third.[/li][li]be less than $50[/li][li]sample at ~50hz +[/li][li]be able to store data [/li][li]be able to connect to a computer[/li][/ul]
[ul]
I’d be really happy if it
[li]were less than half an inch[/li][li]came premade/involved no soldering[/li][li]were less than $20[/li][/ul]

Thanks y’all

Well, i don’t have any real experience with “g” meters, but i am curious, whats your application. On that, this is what i found with the limited knowledge i have, hope it helps.
