What next after using HTC One M7?

Hello, i`m in a big dillema. My HTC One M7 is self restarting and i`m searching for a new phone. But it is very difficult to find something similar. I`m very very happy with M7. Can someone advise me for some similar phone? I wonder is it a good to buy a refurbished M7 for 90 dollars?
Thank you for your oppinions!
