Has anyone used Letterbot? 100% hand written vs. Handwritten font

[John Chapman]

Hey everyone.

I came across this site http://handwrittenyellowletters.com/ and was wondering if anybody is familiar with it? I think ideally it would be great to have 100% hand written letters, but I know that's not feasible or worth the extra time from what I've read... 

This site offers a 100% handwritten letter, mail to and return address, and hand-places stamps inside a #10 envelope. Each piece of mail sent is $1.19

Would this be worth that cost? Any input?

Thanks!
