Tracking exchange price _differences_

[watmm]

Hey,

Just wondering if anyone knows a site or app that shows the differences between the current sale price for bitcoins on various exchanges?
So far i've come across bitcoincharts.com, http://btc-alert.appspot.com, and the Chrome extension Bitcoin Ticker.

Bitcoin Ticker just shows current USD market values, btc-alert just alerts you when MtGox' price goes above/below a certain value, and bitcoincharts from what i can see just shows values over time rather than giving you the current value at each exchange.

Ideally there would be a tool that alerted you when the price _difference_ between two exchanges goes beyond a given threshold, but if anyone knows of something that simply lists the differences that would be great.

There's got to be unix scripts that can read this data, right?

Cheers.

I believe there are some Bitcoin Exchange Arbitrage Opportunity sites over the web... they would provide the info you're looking for. I'm not sure where they are, but should be easy to find with a Google search.

Hrm, that second link doesn't seem to be accurate.
There's also: http://bitcoinwatch.com/

I'm mainly interested in finding buy prices that are lower than MtGox sell prices...
