Sounds a tad bit high... but here's the deal, you may and may not find another one at a lower price, and this is a potential "bird in hand" situation.
You mentioned that it would fit into the "pile-o-guns" you have... because of that, you need to consider what the dollar cost average would be in adding it to you collection, odds are it's less than the purchase price.
Consider this....
Like investing in a stock of a given company over time, you buy some shares when the market and the price of the share price is up, you buy some when the market and the price is down.
Add up the cost for the total number of share you own, add up the total cost you paid for all of those shares, divide the total amount paid by the number of shares owned, and you get the average cost per share... usually it works out to be lower that the highest cost share. And let's say the average cost per share calculation comes out at being $10.00 a share, and now you decide to one share at a current market price of $20.00... you just doubled your money.
Same concept works for gun accumulating or anything else for that matter, for anything that you buy multiples of over a period of time... knives, coins, etc.
Years ago, I came across a S&W 1076 being offered up at what I thought was on the high side. When I went through the calculations above, to see what it's cost average would be by adding it my S&W herd, that figure was lower than the asking price, so I bought it. Also considered, was infrequency of 1076's coming up for sale where I'm at.
Fast forward a few years, and now the selling prices for 1076's have gone way up... and now it looks like I got a real bargain on it.
At any rate... I stopped sweating the initial cost of a firearm, as long as it isn't absurdly over priced, because of the dollar cost averaging valuation method I described above.
Some food for thought and a different perspective to consider.... but I'd go get it.

That's a definite value add, to me.
