I used to use icomoon, now I use fontcustom - using a free tool like that in combination with the noun project (thenounproject.com) I pay for only commercially used icons once ($1/icon usually). What's nice about that as a non-designer is I can prototype for free and only pay when I'm confident enough to move forward with the idea commercially.

I'm not sure what the advantage of a $49/year subscription fee would be when this option already existed.
