As an Arca Noae reseller, I don't have more information than you about products and pricing.
But for video problems and ACPI problems, I will make this comment. It is very useful to developers if you go on to the Arca Noae website and make a good bug report. The bug reports you submit and follow up on make a kind of ToDo list for developers. There is no guaranty that the issue will be fixed, but it really helps your odds.
Also, if you have filled out a bug report, please post a link to it here.
