Well a true upscaler costs hell of a lot of money and really wouldn't be worth it for laserdisc. your TV has a built in upscaler because it has to upscale the source resolution to the tv's native resolution. The Wega Tv should have different viewing modes. 4:3, 16:9, Wide Zoom, Normal, Full, Zoom so if by having a tiny picture in the middle of the screen you mean the video is 4:3 letterbox then just change the setting to the one that will stretch the picture to fill the screen but keeping the correct aspect ratio. The resulting picture you get will be almost as good as any upscaler can produce and will save you a lot of money.
