With this in mind I was thinking of getting the sparkfun bus pirate as it's quite cheap. Would you say that this is a worthwhile purchase?
I really don't know too much about the bus pirate, but it looks like it only has one 10PIN connector on it. It might make it a little hard to interface. I guess you could put it in another socket on the same SPI port of the main page, but I use the SPI SS line to do the triggering so different socket wouldn't really work there.
Another option is the Saleae Logic Analyzer it's is a little more expensive, but I've found this thing invaluable for doing development. I'm sure it's saved me countless hours and easily paid for the $149 cost. I like that the eight lines that can be configured independently to measure/trigger off of SPI/I2C/RS232 etc...
Also their software really rocks! I love the feature that lets me check the timing/frequency of the signals.
In fact, I created a little "Man-in-the-Middle" board I've attached to this post that sits between the GO! main board and module with dedicated pins to connect to the analyzer and show SPI info. On a side note this also has a 4 pin JST connector for programming and a LED for showing IRQ status back to the main board. At some point I'm might make these available if there is enough interested.

I have been looking at Go module development and can see that another tool in people's toolset is a logic analyser would you say that this is he case?

Have you checked out http://dangerousprot...-pirate-manual/ ?
Keven is correct that a logic analyzer is a great tool, and will do more. That being said, the stuff from dangerous prototypes can't be beat for the money. $30 for the bus pirate is very cheap; of course you will probably want to buy some cables etc which will bring the price up some.
You may also like their logic sniffer - http://www.seeedstud...2.html?cPath=75 At $50 it too is very attractively priced.
