With all due respect, umm what's wrong with just buying one?
I mean really...sometimes this open movement (IMO) forgets that software is only free if your time is...if there is a tool out there that can save you time (which is money of course) then just buy it...
paying for software should not be considered heresy...Its just another quiver in your bow.
i assume the developer's paid for the motherboard, cpu and hard drive they are using to build their project?!?
