black Friday deal on Bond Arms barrels?

I always wanted one of the Bond Arms derringers, but the $550-700 price quickly put them on the "nup" list
But PSA did it to me again, with a low end Bond Arms "Roughneck" in 45 acp.
With std grips, recoil is a handful, but figure if I am going to enjoy the recoil, I might as well get a 45 Colt/410 barrel
Seems that is gone.
So what to use to find the bargains in gunfandom?
