Yes, getting Manga Studio EX4 does seem to have inspired a rash of new comics. It's just so dang easy to work with.
Really, if you haven't tried it, do. And yeah, it's expensive, but keep an eye out for sales -- mine was bought on a super sale for $29.99 just before Smith Micro put out MS EX5. It's a great program!

New Note -- Manga Studio EX4 has been updated and name changed. And is now called Clip Studio Paint. I use Pro, as it does everything I need, and I don't see how EX has anything to recommend the higher price tag. It runs just under $60 full price, but watch for sales. And? All updates are free. I suggest going here to see why Clip Studio Paint is better than Photoshop: https://www.clipstudio.net/en/functions/
