Southpa,
$1100 is a much more reasonable price for a Sendero. I looked on gunbroker to see what they were going for there and when I saw $1650 I thought I would mention the custom option.
On the quality of Rem actions, some members unfortunately take liberty to twist words. The 700 isn't a "bad" action. I think and said it is an OK action.
Currently I have rifles in several actions and "I" rank them in the following order.
M70 CRF
Howa/Vanguard
Sako 85
Rem 700
Ruger M77 Tang Safety CRF
I have specific reasons for the rankings and a lot of it is based on what's "under the hood"
If you pick a 7mm or 300 RUM you will be looking at a rebarrel in about 1000 rounds or so. If a 300 WM, maybe 1500 rounds or so. When that happens, you will likely get a custom barrel and have your action trued up, etc. Many people who go this route upgrade the components of their 700 which is exactly what I have done. The basic components of the 700 action are marginally acceptable. One of the first things a lot of 700 owners do right off the bat is upgrade the trigger. I took the time to tune mine myself and they work very nicely down to 2.5 lbs. But they are a PITA to tune and work with.
Although you may get by with the stock components, there are good reasons to replace and upgrade them and not just because you want a fancier fishing lure. If you talk to some reputable experienced smiths, which I have, you will understand this. Do some searching on these forums on building on 700's and you will see what I'm talking about.
All that said, I will never buy another Remington. There have been numerous issues over the years with Remmy's. I haven't had any, but others have.
I am currently doing a 300 RUM build on a 700 action and when it's done it will be a fine rifle. However, when it's done the only original part of it will be the receiver, and that drives the cost up considerably.
Just some things consider.
