I'm using 'Pirates of Drinax' as a basis for a homebrew campaign so picked up The Torpol Cluster to use as additional inspiration, I won't be using the supplement as it stands since I'm modifying a considerable portion of the Drinax campaign.
That said this is a pretty good produce with a good deal of information on the 3 star systems that make up the Torpol cluster. For less than £5 its good value for money - though I'm not sure I'd pay the full price of £8.00 for it.
The illustrations within (epecially the system maps) are useful and the information is concise.
I also purchased the 'Pirates of Drinax Theev' supplement which is also pretty good. If other supplements come out to expand other star systems I'll probably get them as well
