not sure if this is the right forum, so feel free to move if necessary...
what is the going price for sydarms? i know condition would affect the price, so any info would be helpful; also, as far as working on these, are they much differecnt than a standard automag/minimag?
thanks for the help.

Condition=Price.
I've seen ones that need tons of work go for as low as $225.
Like-new shows you at over $450.
From what I've seen, of course.
