I'm looking for a low cost option to hook up a projector across a room using a vga to cat5 extender. I need to know how good the quality ends up being on them and if the resolutions that they claim to get are honest or not. I have to keep it relatively inexpensive since it's for a church.

I'm considering these 2 but any other suggestions would be great.

Geffen EXTVGACAT5142
and
Minicom Cat5 Audio and VGA Extender

I have only used ones from Black Box.  They worked pretty well but we did find that we needed to use shielded cat5 for long runs.

Thanks I'll order one of those up. I found a site with a 45 day no questions return policy so if it sucks I can send it back.
If it works well I'll post back.
