I 100% agree. I generally use a Red 4.7” touch and a SmallHD 702 on my Scarlet-W, and am good with that 90% of the time. Occasionally I just want an EVF for shoulder work or the rare occasion it’s just so bright that the monitors don’t cut it. It’s not so much of a need that I'm going to spend $1000 on a huge ass EVF that’s waaay over engineered for my needs. I want something I can carry with me just in case that is just small and basic for framing and focus. Something I kinda forget I even have until I need it.
I searched and came up empty when I tried to find a true EVF, but the tiny monitor with a loupe thing might work for something not critical. I’ve used some of Feelworld’s stuff and they pretty much specialize in no frills, cheap gear but is good where it counts, and I found this one on eBay just now. Might fit the bill at about $350 shipped.
That one has SDI, which I’ll always prefer, but this one is even cheaper at $246 and is HDMI only:
I may go with the SDI Feelworld...
