I've gone through 3 in the short time I've been an FTA'er- Coolsat 5000, Neusat SP6000, and SonicView SV1000.
All three have very good PQ. The best of the 3 seems to be the Neusat. But, my favorite overall is the SonicView, followed by the Coolsat and Neusat.
I've been primarily using the s-video output of all three. But, all three do have component outputs, which is nice if I need to use the FTA with my LCD projector. I just can't give you a comparison of the component outputs, since I haven't been using them.
