You know, I don't mind paying for add-ons, but let's call a spade a spade here.  This site 'Donationware.net' is offering planes for a 'minimum donation' of $5.00.  Now $5.00 is not a lot and it is for a good cause, but calling it a donation is ridiculous.  They are forcing you to pay to get the plane, so they are selling it, plain and simple.  It's just trying to make it sound like you're doing this noble thing by buying it and if you want to pay more than the listed price, then you're welcome to!

Is it just me that thinks this is a load of diaper filling?
