PPC Engine Script? (Alt to hyperseek)

I've run several websites with Hyperseek over the years, and paid thousands for several licences, with the "top" level version (source code etc) of the newest version.

** comments about people removed **

Anyway - after having the licences sitting there collecting dust on three of my domains because a few of the bugs are just too big to let slide, I'm looking at other scripts that might work for me.

Does anyone have experience/knowledge of some good but reasonable ppc search engine scripts?

I have a cool idea that I'm ready to get out, but *really* don't want to launch it with hyperseek and then have endless problems after the fact. (Been there, done that, don't want to face that again).

So far the ones I've been looking at are: (none of these are affiliate links by the way, just the sites' links)

Inout ppc (Inout PPC Engine - Popular PHP + MySQL based PayPerClick(PPC) advertising service PPC Engine Script)

ES professional ES Professional Pay Per Click (PPC) Search Engine

Smart PPC SmartPPC Power Search Engine Script | PHP Search Engines | Hot Scripts

- unfortunately this one won't load properly, my f-secure says its known for harmful activity (?). (It may not be the case but... thought I better ask)

Reviews on any of the above or other ideas?
