Question : how to easily find table scan queries

I have a very busy CPU and sql server.
Through Perfmon , I was able to find out that there are a lot of Full scans happening.
Now how do I identify which sql statements are doing these full scans.
I have used sql trace and captured heaps of sql statements in short periods but the problem is that there are heaps of statements.. i cant go through each of them , execute them and see execution plan to see if there is a full table scan..
Is there a easier way to trap table scan queries... ???

Answer : how to easily find table scan queries

On SQL 2K5, this will give you the top 30 query plans with the most logical IO which will probably equate to most table scans. If it does not, it will still probably tell you what needs attention.
