Although Camp Simcha is an extraordinary camp, I would not include it in the same catagory as many other struggling and deserving mosdos listed above. Camp Simcha has huge resources, both private and government.
Having said that, I think that there are 2 groups of people that can answer the question as well as or better than any of the above.
1) Rabbonim and 2) some of the better known g’virim who have ‘hands-on’ experience with tdedoko organizations.
