Should I go PPC

I tried Adwords - should I try someone else

[surfgatinho]

Hi
My only experience of PPC to date is Adwords and I can't say my ROI was really worth it. I got a few clicks but I don't think the sales were that great.
I'm in a fairly competitive area with a low conversion but relatively high selling prices.
Anyway my SERPS are good for many keywords in G and most in Yahoo.
What I'm wondering is how much would using a different PPC engine affect my reach and any reccommendations for which.
I'm sure there must be some way to make this work as I see a few of my competitors doing this, but then I'm beating them in the SERPS!
Thanks
Chris

In one of my areas where I sell software I can't get Google to convert into a positive ROI for the life of me while on findwhat and overture I am doing great.

I think in some areas either my product or my ability to write ad copy is limited by the shorter titles and/or descriptions.

If you track your campaigns in detail I would definitely give overture and possibly findwhat a shot.
