I have a budget of $150 and up. Best premium theme for technology news and how to type article site. Like metro themes magazines and other cool theme.
I agree with now spending money on a premium theme. Start with a free theme that has custom features for example http://www.healthinformationtechnologycareers.com/ and then you can always upgrade easily if you need to.
The criteria of saying beautiful is different from person to person.
Again, its not always true that high cost and yield high efficiency with better performance.
The question is flawed - theres no such thing as "best wordpress theme", regardless of cost. Choose a theme that appeals both in appearance and functionality for you. No one can choose that for you.
Not what you wanted as these are free - but possibly more versatile:
If you want to run a serious news site I suggest not to use any "premium" theme at all but create one yourself.
Or in other words: You are better starting off with some free theme and advance from there towards making WordPress your own. It doesn't really make sense to spent money on something which will limit your "usability" of WP in the long run.
