We've bought in Ciftlik and we love it. It is a bit further out though and, whilst there are lots of dolmus and a city bus in the summer, I'm not sure what you'd find in the winter so transport is probably essential there. There's a fantastic pide place and somewhere you can buy ready cooked chickens that are delicious. Melissa, the local supermarket, is great and surprisingly not really any more expensive than the larger supermarkets. Market day is Thursday and happens opposite the Melissa. PM me if you'd like me to email a few photos. There's not a lot on the internet about Ciftlik to be honest.
I've heard great things about Koca Calis from the people that like it. We thought it looked good but didn't find a villa we liked when we were looking. If you're after a place that's quieter than Calis but doesn't necessitate owning a car then you might look at Gunlukbasi. We'd have bought there probably if there had been anything available. Really happy with Ciftlik though.
Good luck.
