Bad experience(s), you learn from it, not run away.
Sorry to hear your bad experiences, I had a bad experience with HID Tech as well in the end. However, this doesn't deter me, it just makes me want to conquer it even more. I may not be into HID like I use to a year ago, but I put a lot of my time into it so I could be better.
Give it another try. Patience is key.
