If you do a search for the LiteOn 411S on Ebay, you’ll find an internet only dealer by the nameof Ascendtech blowing these out for $40. I bought 2 that came in 2 days and are both 811s models now.
Flawless transaction and great service. I think the seller ID is asendtec if you prefer to search that way. BTW, they are Gateway OEM units, p/n 5503029, and unopened.
