Has anyone had experience with nsphere.net?

We are always open to new advertising ops and just recieved an email from nsphere.net and I was wondering if anyone else had had experience with this company.

Thx

I was looking for the same and found this: http://www.seomoz.org/q/company-nsphere-www-nsphereinc-com

The lack of pricing info and the sort of confusing interface with no direct upgrade options on the free version was enough for me to assume that it is probably a little shady. The sample directory in the above mentioned discussion confirms that suspicion.
