Not to sound like the rifle's father, but....what are your intentions?
Do you plan to hunt with it? If so, I think I would pass.....you've said it's not a heavy rifle, so it will probably kick like a mule with attitude, and as you already said, ammo is expensive (and probably hard to find to boot).
Also, it may be pretty now, but after hunting with it a few seasons, I'm pretty sure that it's going to be....well, not so pretty. One thing I hated was hunting with my buddy when he brought along his Browning Citori.....he was so afraid of scratching the finish that he held the gun under his coat while hunting....needless to say, he never, [I]ever[I] bagged a grouse or woodcock with that gun.
Are you just going to use it as a shooter? The rifle might stay pretty, but your shoulder will probably need a heavy dosing of Ben-Gay after a range session, not to mention that the ammo (and probably reloading components, dies, ect) are expensive and hard to come by.
Finally, are you buying it as an investment? MIght not be a bad deal....you can
probably get your money back out of it, and then some.....but in this economy, there isn't a whole lot of buyers (at least in my neck of the woods), and they are ALL looking for bargains......
Just my thoughts and point of view.....yours may vary!
