I haven't seen any SP101s locally since the plandemic was implimented. (England said this BS is over BTW
)
OP, I think gunbroker is your best bet if you want one any time soon. My wife paid $399 for her 357 magnum used a few years ago. I think those prices are gone forever and you'll have to pay what seems like new price for a used one. A good, moderately used SP101 should last a lifetime and 1 hour worth of work can make the trigger pretty darn good.
