I was in the same boat as you recently, I wanted to try one but didn't want to spend a lot on it either. I was able to score a brand new Darbee on ebay for under $100, so I figured I'd try it out. I can say that I'm impressed with the results and would recommend it. My recommendation is based on having a projector with a 120" screen, I can't comment on how well this would work for someone with a tv. The Darbee does not affect color accuracy or brightness/contrast, it only enhances the current image at the pixel level. You can adjust the effect in 5% increments up to 120%, I leave mine on the HiDef setting at 80%. When switching the processing on/off you can definitely notice a difference in sharpness, detail, and depth of picture, but it's nothing unnatural looking. I would say it's definitely worth getting, and if you don't like what it does for you then you can always sell it.
