Remington has had a rough time lately. I think you can do better than the 783, but would prefer it over any 700 from any era. Every 700 and 600 series rifle including the 721,722, 7, 600, and 660 made from 1946 to 2014 came from the factory with a flawed trigger design. The 2007-2014 rifles have been recalled. The older rifles will be dealt with as soon as a judge decides which direction to go after recent lawsuits. It may be a recall, buyback, partial refund, etc. No one knows yet. I wouldn't own one unless I replaced the trigger with an aftermarket trigger.
The 783 is Remington's latest attempt at a budget rifle. The 1st, the 788 was a very nice rifle, but it had a short production run. The 710 and 770 came next and were disasters. By all accounts the 783 is a decently made budget rifle that shoots well. But the reputation of it's predecessors hurt it's reputation. If it is a used rifle at a good price you could do worse. Most of the scopes that come on those are next to worthless so don't let that figure into the value. If buying new I think there are better options. I really like the Ruger American rifles that can be had for under $350. But they aren't the only option.
