I've gone through a *lot* of survey places over the years... and although I've ditched most of them for whatever reason, Pinecone is one that has always been consistent and without a problem.
I didn't like when they went from "automatic pay each time you complete" to the point system, but then I realized that it's the same $3 and I just have to order my payment. (And considering other survey places pay pennies, that's a mighty good pay rate!)
What I do generally is just do the surveys as they arrive and then cash out every so often. I checked about 2 weeks ago thinking I'd have about $18 saved up like I cashed out for a few months ago, but there were a few product testings (so double payment for 2 surveys each) in there, and I found $39 in my account.
Cashed out quickly and was paid within a few days... so it definitely remains a favorite!
