The weakness is in the price. Wow. That's, what ... better than $700 in USD?
I think that's the donation price (actually something like $1000 suggested donation IIRC). That provides the stuff/hardware, support for an organization that's ready to deploy at once, and transport to the place it's needed. When you break all that down, I guess the price makes a bit more sense.
Also, I believe they customize the kit based on what's needed. Perfectly reasonable approach, I think.
Not that I have any first-hand experience with the stuff in the kit. The list seems right, and if the quality is good, I'd love to take it for a test drive (I'd pay shipping). More seriously, though, maybe they should ship one to Mr. D.R. for a close, unbiased look.
