Thanks for this, too. 
For Rebrickable I have a best-guess connection throttle algorithm which seems to work most of the time (which results in horrible timing for large part lists).
There are other sites with "part out values" like brickmerge.de - somehow they must obtain part prices... Does anybody know how? Thanks in advance.
