I have the original Analogue Nt, it's really just an expensive NES with a new PCB and HiDefNES installed, works great but I rarely use it.
You could get an original Famicom/NES with HiDefNES installed or have someone install it for you.
Personally I'd rather go for RGB mods on my consoles, and use OSSC/Framemeister for the upscaling.
There's several cheaper options available as well, like Retron 5, Super Retro Trio, RetroFreak etc.
I think they all play Famicom games and have HDMI output, but probably just upscaled from analog?
