Thanks for the recommendation on the Aphex. I saw several people praise it for tone, but there is a question about construction/reliability. If I had seen one back when I was looking for a good deal, I probably would have given it a shot.
I picked up a used Trace SMX dual compressor pedal a few days after the original post and it seems to work quite well. I think I may still keep an eye out for a super deal on a Demeter, but I will stick with this one other than that.
