I've done a lot of self filming, easiest route is something simple, that's basically all automatic, no ND's, no aperture, iso or gain settings. I've used a Sony Handycam for my solo apps, nothing real expensive 800.00-1200.00 range.
I used to just run a cheap Vanguard ballhead tripod, it works with the right tension and is lightweight and discreet. I use Manfrotto fluid heads now, but all of my equipment has massively upgraded from just 5 years ago.
