just to add...the differences between the scalers (if any) will be very small. Today's plasma units offer very good internal scaling. I have tried the DVDO and Focus Enhancements products on my display and saw very little difference. The NEC was superior to the DVDO, while the Focus Enhancement was slightly superior with the 852 x 480 format. The enhancements were so small that I put the scaler up for sale and now use the NEC as the main unit.The trick to a great plasma image is clean ac. Filtered ac can do wonders for a plasma video image. Of late I have been involved with a OEM project for a scalable dvd player. I was very impressed with the 1080i output into the NEC. The big selling point for me was the sharper image and color saturation. A couple of days ago I just put the finishing touches on a new power conditioner design I have been working on for 120-240v applications. Prior to the power conditioner the OEM player surpassed a EAD TheaterVision dvd player I have in house that uses DVDO progressive outputs. After I added the power conditioner the EAD was the equal to the OEM model. The image was sharper, more dimensional, and had improved color saturation. My point is there are lots of ways to improve the image besides scaling.

Ok, that's fair enough. Actually, I forgot to note another reason for considering the iScan scaler/line doubler would be to convert from various sources - Svideo, SCART, even composite - into component so there is only one run of cable snaking its' way through my rafters and down to where the plasma is going to hang from (it'll be hanging over the fireplace from the ceiling).
you are not worried about component video with a plasma display, the important issue is that your input video source matches the display native resolution. the nice thing about using the internal scaler is that it will convert your video source to the native resolution. if you want to purchase a scaler then i suggest something like a nrs that matches the native resolution. any old scaler like a dvdo will not match the native resolution. one of the big things we did with the dvd player is we made sure we covered plasma resolutions. right now we offer 852 x 480 standard via the dvi output. our component allows you to flip between 480p, 720p, and 1080i. most outboard scalers only output 600 x 480m (typical dvdo circuit).alan
