We were in Turkey last summer...cheap pensiones, cheap efficient buses get you around the country. Went from Istanbul-Konya-Goreme_Istanbul. Get the "Lonely Planet Guide" to Turkey, and make sure you get yourself out of the typical tourist trap of only going to Istanbul / Bursa!
...and watch out for the Gypsies in Taksim Sqaure of Istanbul...they will try and distract you, and while you're busy talking to them or turning to buy bird seed from them, their mates are robbing you !
