I opened one w/ Vanguard Charitable in 2006/2007 when I had 2 very uncommonly high tax brackets those years, and plunked some money into the DAF.
Vanguard has greatly increased the options available (they used to have just 3 investment options when I first started - now they have something like 8 or 9, including 2 or 3 international).
With Vanguard, their only 'requirement' is that they ask that you make at least one 'grant request' once every 7 years. Overall, the entire Vanguard Charitable organization must give away a certain minimum %, but they are well over that with everyone's donation patterns. I've been slowly making grants over the years, and managed to make a great move by shifting 1/3 of the account from cash to equities in March 2009! Definitely has helped grow the account for the benefit of my fellow neighbors.
There are other DAF providers, but haven't researched them lately (Schwab, T Rowe Price, I think even Royce funds offers a DAF). At the time, Vanguard Charitable offered the lowest cost combinations (surprise, surprise
), but they were all fairly close. VC is a completely separate organization from Vanguard, but they offer Vanguard fund investment choices.
They do also accept gifts of stock. Just check their deadlines - might be December 1 for stock contributions.
