looking for a good alround blue ray player..........

have been thinking about the oppo 103 I think it was, but just brought a new 4k tv...... heard about the new sony which is in my price range but it doesn't do the 4k yet.   any suggestion would be helpful, no extravagant priced systems please, I cant afford them.  want something that can play all the cd formats, though    thank you in advance.
