My two favourite EDC sub-$100 Spydies:
Translucent blue Manix2 (CTS-BD1)
and/or
Endura 4 FFG (VG-10).
They're both a good size for my liking, not too small, but both light to carry.
I've been carrying the Endura 4 every day for a long time now, and I just recently got the Manix2, which is even lighter but just as strong.
They both lock up strongly, have a good easy release mechanism, and have good blade steel that holds an edge well.
Neither are collectors items, but good functional blades.
