It's the same as with any other camera: don't forget to pay :bsmilie:
Set your budget, check the shop prices. Contacts for photography shops are in equipment section. Check that you get a local set (not grey sets / sets with shop warranty). For someone not familiar with the topic it's best to have warranty services from local Service Center.
For everything else: check the proper function, zoom, etc. If it takes snaps in the shop it will be fine. If you want to take videos do read up about the required speed rating of the memory cards. The included memory card might not be good enough.
Check the price guides for shops, recent prices (if updated) as well as addresses and phone numbers. Take your phone, give the shops a call and ask for the prices. Some offer e-quotes via email (valid for 7 days). Don't get carried away with freebies (memory card, funky tripods and other stuff), mostly cheap things or you will get the proper type later anyway if you need it.
