I got mine at Harb's ski systems shop. It was an excellent choice. remember, when you go to most good boot fitting shop, they are typically not going to be competitive with internet prices, and more than likely near the normal MSRP for the boots. This is because they are not making sales on volume. They are providing a service that you cant get from the internet. Also, dont get sized then go buy on the internet then get fitted, again you are undercutting their service that they provided you and the time they took to find the right boot (this step alone can take 30-60 minutes!)...if everyone did this, most shops would end up closing...
With that being said, Im sure you can go to any boot fitter and tell them the most you want to spend (of course this will start limiting your options). Do you plan on skiing a lot? There is no single piece of equipment you will buy that will turn you off skiing then bad boots. Boots will last for a very long time so if you plan on skiing a lot and for a long period of time, the investment is well worth it. You can buy new liners when the factory one wears out.
Just to give you a point of reference here was my cost and setup:
$950
Nordica Doberman Pro 130
Alignment
two plates - This was required because I had a "high invernium something or another" basically they ground down the sole of my boots. added on these two plastic plates then planed them to get an 2.5 and 3 degree "wedge" on my boots so my boots when standing on the ground look like they are tipping in towards each other.
While this seems expensive at first there are two things to consider. First, this setup should last be for a very long time (with occasional replacement of the liner). Second the Dobermans are considered "race type" boot and are also one of the most expensive boots Nordica makes. Third, my previous boots which I just bought off the shelf at some ski shop were two full sizes too big and even though they were that big, they were painful to wear!
Don't skimp on the boots, I'd forego buying skis if it meant you had more available to buy boots? and then just rent skis?
