Then you have been looking in the wrong places. TM pistols can be found under 300$ quite easily. To fix your listing:
KSC -> High.
KWA -> High (mostly the same products as KSC but with cost cutting on a few parts).
KWC -> Very low to mid depending on model.
KJW -> Mid, usually pretty durable too.
WE -> Very low to mid depending on model. High lemon rate.
WA -> High but mostly unavailable in Canada.
TM -> Highest quality.
Keep quiet. Sound travels faster than BBs.
