I know it sounds hilarious but actually I still have no digital cameras on my hand other than my phone . I never owned one since the promotion from shop changed so quick, almost every new models per 2-3 years and so I am not confident to give it a try. And then once I am ready the news says another model is coming out next half year. 
This why I whish to look for a used one. I wish a recent model , just basic with RAW output and enough adapters allow me to play with my old manual lens collection. I have seen many used are selling on internet and even local, but what else should I check other than checking the shutter count?
Thank you,
