I can't remember the name of mine, but I'll post it tonight.  It was
abotu $80 and does come with asmall remote and will convert up or down
resolutions; but I just use 640x480.

I'm no EE, but its not quite as easy as to ask what the real resolution 
is.  There are intentional scan lines above and below the signal that
are usually not displayed on a TV, the interlacing complicates things 
a lot, and then you have NTSC or PAL.  I've always heard 640x240 and
then interlaced to another 240 lines is about all you can expect.
