Another link wheel question :)

So, I'm quite liking these link wheels and after making my first one I want to try and get the 2.0 properties indexed as quickly as possible. So I was thinking of writing an article for each one and uploading to ezine / goarticles. I was then going to add a link back to the web 2.0 property. My question is this, will it be ok to also add a link back to my money site in the same article? or is that going to be over doing it? The last thing I want is to be penalised!

thanks
