I have a site that lets you search Omaha/Holdem tournaments in Vegas this summer:
http://www.rainbowspuppiessunshine.c...ournaments.php
Use the left column to filter the data. It uses my SPoints methodology to score each tournament's structure. I don't keep track of starting stack and level data, but I do use that data in generating the SPoints. Click the About link to see the formula behind SPoints.
Other than that, you will have to dig through structure sheets yourself to find the data you want.
