Unfortunately, I think his answer still leaves the blank question of what "it" is with the Rack/Control. The two units are separate products when purchased, registered, and (usually) warrantied. However, the blanket cost of the Extended Warranty is a quarter of the cost of the Control new. I need Frank to clarify how this works when he can. Not really in a hurry, but I do intend to buy the Extended Warranty. However, I could not pay $100 per yer on the Control Unit alone, when I only paid $400 for it new (and possibly got a discount from vendor). This would mean the annual Extended Warranty cost of the Rack/Control would be $200 (two separate Warranties) where the regular Helix is $100 (only requires one warranty). They don't mention any "warranty packaging" for these two, so its a confusion at this time for me. I appreciate your passing this along. I think Frank will have to explain it. He mentioned he would reply to this thread.
