Buying for Cython support?

I have been using PyCharm CE for a while, and it is the best Python editor (and perhaps the best IDE) I have ever used. The problem is, Cython support is exclusive to Professional Edition. I went through the list of additional features provided by the professional edition. I don't need any of those additional features except Cython support. I'm not sure if the pro version is worth buying just for the Cython support.

Any thoughts or suggestions?
