Rt,
Send an e-mail to Walter (Underwoodwally). I think he is still affiliated with the folks at AV123. He may be able to share with you the origins of the Onix player and tell you which big dollar player shares the same platform.
Of course, you have to realize that Walter may stand to gain from your purchase of the Onix, so consider that in your choice. However, I've bought several items from Walter over the years and he's always been very helpful when I've asked him questions.
The 30 day trial makes it an easier decision. Buy, try, keep or return. Easy enough......
