That seems mighty steep for a M-30, one can readily find Marlin 336s in that price range and, with a little looking, even the 24" barrel, 2/3 magazine version. A 35 caliber and especially 32 Special will run more but the common 30/30 is much less.

I would see what the "wiggle room" is, even 25% off would put it out of my price for a Glenfield.
