We've been attending meetings regularly for nearly 2 years now. Like worldgonecrazy says, their meetings are held in silence, with any inidvidual standing up to say something if they feel compelled to do so. you may get 60 minutes of silence of 4 people saying things.
you don't mention taking children but if you are, check what activities they have for children, if any. Our meeting only has "family" worship events about every 6 weeks, so we just take DS in for the last 15 minutes the rest of the time.
I've nevr found people standoffish at quaker meetings, and we've been to three different meeting houses, people tend to be very welcoming. Our meeting has name badges and everyone has one, including our 3 year old who is hugely proud of his.
They do focus on equality - they support gay marriage, have always supported women's opinions as being as valid as men's, we have members who are gay and a transvestite who comes along either dressed as a man or in a frock, but he's still welcomed however he dresses.
About the thing about some being more equal - people are either attenders, who just come along, or members, so they've applied for membership and can vote at business meetings etc. some of the members will also be responsible for opening up the meeting venue, arranging refreshments, holding meetings outside of the weekly meetings for workship, so they will be more involved, but are not actually any more equal than anyone else. I have as much right to speak, and be heard, as the person who runs the social justice group on a Tuesday night, she just does more within the Quaker movement.
Go for it, I went once because we had planned to go away for the weekend but it snowed so we couldn't travel and we've never looked back.
