RE: which one??
If that marlin is as much as the remington someone is getting ripped off. You should be able to get a marlin or a savage for around 200 bucks or so, and the savage will come with the accutrigger. You can get a bit nicer one if you wanted to spend more money, and they offer more choices in the 17HMR line up.
If it's between those two guns for the same money it isn't even a question, get the remington. It's a much nicer rifle all the way around. Like I said your either getting one heck of a deal on the remington or getting screwed on the marlin.
