vga out hd set top box for loewe aconda

Looking to get 1080i from a loewe aconda any suggestions about a quality hd set top box or other suggestions to completr 2 channel video and stereo set up. The older loewe only outputs 1080i with vga input.

Doesn't it have RGB component inputs? I ran mine that way from a satellite receiver. However, the tube is not physically capable of rendering the full 1080, IIRC.
Thanks for your response and you are correct can only go up to 480p with component and again with also an antenna on the roof for local hd reception 1080p I am looking fo a good sat receiver compatable to the loewe if not I will compromise and settle for 480p.
