I do a variety of panoramic formats. I've never done the half-darkslide thing - It just feels like too many opportunities to introduce dust onto the film and operator error. I have the following cameras that do panoramic photos:
Canham 5x12 (probably the best option of the cameras I have if you want to do serious panoramic work, but definitely not budget friendly, nor is it compact or lightweight)
Vermeer 6x18 pinhole (one of the coolest, uses 120 film but you only get 4 shots per roll, plus the hemispheric film plane can create compositional challenges if you aren't paying attention)
Reality So Subtle 6x12 pinhole (another more compact panoramic camera, with a similar hemispheric film plane as the Vermeer, with similar compositional challenges)
Horseman 6x12 w/65mm Rodenstock lens (love the camera, but another definitely not budget-friendly option unless you get lucky like I did)
Holga Pan 6x12 panoramic (very budget friendly, with a lens a Holga fan would love - definitely some mild vignetting in the corners, and some blurriness/loss of sharpness in the corners, but not as much as you might want for a Holga).
A possible best-of-most-worlds solution for you might be to get a Holga Pan, remove the lens, and replace it with a vintage Schneider Angulon f6.8 90mm and a helical focus mount (or you could even set it up as focus-free and position the lens to give you infinity to a couple meters at f/16). Then you'd have a lightweight, inexpensive, portable, yet optically sharp panoramic camera.
