Anyone who can suggest me a good template for tutorial-blog?

Guys, I am running a small blog on MS Excel and it has been long since I updated it. 

But now I am planning to restart posting and reviving a bit. But for that I need your help by suggesting me some good Wordpress templates for a tutorial-blog. 

My blog's name is ExcelMatic (please go to my profile and get the link).

Thanks in advance!
