I am a serious buyer. If you have one and are willing to sell, contact me asap. Here are the details on it:

I believe they also may have been branded by Sun and Daystar as well.
If you don't have one you can sell me, but you know where I can get one, or if you know somebody that has one, or if you know a good place to look for one or make my interest to buy one known, please contact me asap.
