Thank you for your post.
You could use the PS3000 range, however this is only capable of streaming at speeds of up to 1kS/s. This therefore would not be fast enough for you. You could however use it for the larger buffer and longer record time, but this would not be streaming.
I would suggest that the PS3000 is the best range to use as they have a better streaming capability, bigger buffers, and faster download time to the PC.
Hope this helps
