@John,
I only had a few JV's and never had those problems. I've read some of your posts here and elsewhere and obviously you are more experienced, had more JV's then myself and had seen all the colors .

I've gained my marketing experience offline but as Paul sings "people are the same wherever you go", so I would try to connect only with JV's that are in my niches, that gained their reputation as knowlegable and honest people. If I FEEL that I will need to go thoughout the buying process in order to see if there's a hidden step that I wasn't aware of, I wouldn't take the JV proposition.

Good JV's are just like good friends and believing and mutual respect is crucial as in any relationship.

Of course every JV's proposition has it's potential and I would take a look at any of them and there's so many kinds of JV's as @Rob Toth wrote, but just to outline my basics, Usually I will try to JV with product creators that sold me a product once and that I was happy with their product and support.

Never with those whose jumping on new niches every week. I just can't believe you can be productive, with good content, great and reliable products and support on 15 different niches, (building my business reputation is far more important then a couple of $K's at the moment) and if they do, so they don't really need any JV's as they've already got the money and human resources to cover the marketing side.

- A long time collaboration, if it results with good sales so neither of us would like to end it.
