Big Daddy - anyone out there use them?

I've started getting sales pitches for the following site;
http://www.searchbigdaddy.com
Has anyone used them, if so what do you think?
I checked the site this morning and it says "Down for maintenance"

Personally, I don't pay for any search engine placings, but if you do think you need to go down that route, I would suggest investing whatever budget you have planned with the well known big boys (google, yahoo etc), rather than giving a little bit to each of the miriad of small search engines out there, who may well rank you high in exchange for your pennies, but are pretty useless if nobody actually uses them.
A good rule of thumb is that if they need to come knocking on your door, rather than you approaching them, then they may not have much to offer, other than relieving you of some hard earned cash.
The one exception would be if you are in a specialist trade, and your want to get listed on a specialist search site.
