Personally? Yes. If they're throwing their "love link" then it's minimal if they have a number of links on the same page. And if they're not throwing "love link" (not using NOFOLLOW tags) then what's the chances that your site is going to be clicked on with so many other links on the page? Really, they do limited results if anything It does get you another backlink (as long as google doesn't think you PAID for the link and get blacklisted), but that's about it.
FFA links are another that is just something that doesn't work. What works are links that are relative to your business linking back to you. You'll get more points at google if a web designer is linking to a web hosting company, than you would if say a site devoted to how chalk is made and then suddenly they're linking off to a hosting company.
At the same time, google is a computer, it's not a people policed network, so there are some things you can get away with, but it all depends if you want to go with Blackhat SEO or WhiteHat SEO. You're much safer gong whitehat with a shade of gray every now and then
