OP,
Have you thought of picking a used Sony/Pioneer bluray players from eBay and using that to extract DSF/DFF files from your SACD and then using an external DAC to play them? The initial outlay for the bluray player should be between $30-$100 depending on the condition. Then you can get a great DAC in your budget.
The only part that needs a bit of time is to understand the process of how to rip the SACDs using the bluray player. It's not that difficult.
