Missing key features and way too expensive

I’ve been trying out the free version. nozbe does have a lot going for it – it lives up to the motto of simply get things done. I like the interface and how straightforward it is. But the lack of good gmail integration (see todoist or rtm for a better implementation) and the lack of a rapid task entry system (e.g., todoist’s launchy plug-in) are fatal flaws in my book. And I really can’t believe the cost – no way can I afford $90/yr for a task manager. $25 or $30 is about the max I’m willing to spend for a subscription like this. I really don’t get it – GTD is not just for rich executives…what about all the working moms out there?
