Still, chinese shit CAN last if you take care of it and install it correctly. Make sure you install the ballasts in as safe a place as possible.
For example, don't install them in an area where water can collect on them. The China made ballasts usually have openings on them where water can enter and ruin them. Install them UPSIDE DOWN so that if this does happen, water won't just sit on the plugs until it has an entry point. Also, I'd install the ballasts where some moving air can touch them, HEAT is another element that causes failure. The last thing, which is something you can't do much about, is VIBRATION.
Or, just drop some $$ on good ones. We all know Supra owners are cheap bastards though.
