I'm in Chiang Mai and the CDN Consulate is 10 minutes down the highway so for me, no issue. It's all about perspective I guess, and I dare say that 800k baht is an amount not to be sneared at. That's why the agents do as well as they do handling affairs for those folks who don't have that in their pocket.
Coincidentally I'm off to the consulate office shortly to get exactly that letter of income for my retirement extension.
