No doubt people are regretful if they only got a head-mounted computer for this amount of money.

When I needed FPV glasses, I got myself a 20 € screen from AliExpress (resolution 800 x 480, this would be 100 € if you wanted 1920 x 1080 pixels), a 7 € Fresnel lens and a 7 € plastic headset.

Some cutting of plastic and 3D printing later, I connected a 39 € Raspberry Pi (with a 4 € memory card) to the back of the screen, taped the whole kit over with aviation grade duct tape (just kidding, ordinary fiber tape)... connected a flexible USB power cable to my 10 € battery bank filled with dumpster-dived laptop cells and a year later, I still fly with them. Nearly everything else has crashed and burned in various ways, but the glasses hold together. :)

For 3500 euros, I would expect to get 2 ground stations with double headsets and 4 drones with 100 km range. :) Or a working car, not a new one, though.
