I hear you. I used to have a nice Digital SLR but I found it like a "look at me" beacon on my travels and drew quite a bit of unwanted attention. If I get more advanced on dtube, then I would definitely reinvest in a pro camera... Im thinking a compact mirrorless with Leica lenses.
Right now I am only upgrading my equipment with my dtube earnings. I like to keep it sustainable on that front and I will vlog about that as it happens.
Im looking forward to your filming tips videos :)
