Yard Sale Dilemma

To try to sell or to just give away... that is the question. Whether 'tis nobler...

No, no Shakespeare drama needed here. But right now part of my decluttering paralysis is based on this question. So here's my little self-debate.

Yard Sale/Flea market/Other sales method.
Pros: earn a little money from the stuff taking up space that I don't need, use, or love. I gain not only freedom from clutter but also get a bit of money out of it that can be put toward the vacation we're saving toward for next summer. I also think I'll be more motivated to get rid of things if I think I'll get something back for them... a bit more ruthless in my cleaning out if I'm trying to fill a table, have things that catch people's attention, and if I can convince myself I'm turning it into something (money) that I'll use for something I really, really want (extended vacation in the US).
Cons: Time and energy. Probably the best way to do it would be to get a table at a regular flea market here, but it would take a whole day of sitting at a table. Relief would be difficult as one of us would need to be with our daughter, or alternately we could use a precious babysitter opportunity to do it. I've tried listing a couple of things on Tradera (Swedish ebay) using a student discount so I can list 1 item for free per month (until Sept when my student card expires). But even that takes the time of taking photos, creating an add, and assuming it sells then packaging it up and shipping it. I haven't had a yard sale since I was a kid, and then I'm pretty sure my mom did most of the work... so I really have no appreciation for how much time and energy goes into preparing, pricing, etc. But it sounds like a lot.

Give it away
Pros: It's quick and easy - put it in a box and take it somewhere. I can get rid of things a little at a time instead of storing them waiting for one big sale. They would hopefully be a blessing to others who either receive them for free or can buy them second hand inexpensively, and that money used for good hopefully too. All depending on where and how we choose to donate. This is what we've always done so it's familiar and comfortable.
Cons: I really have no idea what things are worth and sometimes it's hard for me to give something away if I think it might have some value. It's as though somewhere deep down I feel as though I'm being cheated somehow. And as long as there seems like there's a chance that we could earn some money this way, there remains a certain allure with trying the sale method.

So weigh in and help me decide what to do. What are your experiences with sales, positive or negative? All thoughts welcome!
