Run away from the model 25 as fast as you can and don't look back.
Model 10's and 12's can be had for as much as you are looking at paying.
One of our locals bought a model 25 with a scope at our local shop for under $800. $900 for the rifle alone is a gouge.
Any of the following would be better than what you are currently looking at:
(All prices from P&D)
Remington 700 SPS Varmint, vented, BT Stk 223 Rem. 750.00 NEW
Remington 700 Varmint, Blued Brown Laminate 223 Rem. 899.00 NEW
Savage 10 Predator, Synthetic, Winter Camo 223 Rem. 875.00 NEW
Stevens 200 223 Rem. 440.00 NEW (Get a Shilen from Mystic Player for $400ish and your WAAAAAAY better off than any of the factory options listed)
Tikka T3 Varmint, Stainless Synthetic 223 Rem. 1,060.00 NEW
Remington SPS Tactical 223 Rem. 825.00 NEW
At least all of the above can be upgraded in future if you wish.
Here is a much better rifle than the 25 for $100 more plus another $30ish for shipping which is less than you will pay for taxes on the $900:
