Intuition has something like 15 different alpine ski boot liner models. You need the right model chosen for your needs. The wrong ones will never be right and might not even fit your boot volume. The right ones can be very good.

I've used Zipfits with good results.
Where do the Tecnica and Nordica lines diverge? They are the same company. If some of the models are identical except for color, that might offer a chance to hunt for a better price on a preferred model from the other label. (The same might apply for Lange & Rossi, and Salomon & Atomic.)
Aren't the September sales the best time to buy boots? The retailers have their new stock plus the left overs, and they want some cash to start paying for that new inventory, so prices can be good. I think there's a better chance of getting the best boot for one's feet due to the wider selection.
Phil, please explain your comments about the Harb Alignment Center boots. My main ski partners (four) all are on their boots (Head & Dalbello) and fitting & alignment with great results. My Harb footbeds have worked very well for me.
