Welcome along.
A good place to have a look is the European sub-forum of subaruforester.org
Have a look at Scc28's car if you need inspiration. His XT is a very good example, though he's probably gone further than you are looking to.
Cars do go up for sale in the European Marketplace too, so that's something to keep an eye on. You could also post a "want to buy" thread, which can help as you have a load of forum folk keeping their eyes peeled for you and anyone looking to sell may contact you before posting a for sale thread.
Hope that helps.
Good luck with the search. They're great cars. I've had my FSTi over five years now and it still brings a smile to my face!
