You are hitting the factory ramp up for the holidays. They build for the big box stores first as that is the main source of sales distribution. I had a delivery date of almost 3 weeks for my 5575 and that was early October. If that is too late for you then try one of the big box stores for the system you are interested in.
And thanks to ejn63 for the answer from a similar question in the forum.
We have one store here And it sadly only has the expensive one. Also I can't get the student discount there... but other firms are building up as well and they can still deliver online within 1 week or so.. well, I'm sad but I'll have to get a different brand that ships faster
