I guess much could depend on your disposable income. If the rifle cost is a minute fraction of disposable income then I can see a situation where cost would not matter to the purchaser and a purchase could be made without a second thought. As disposable income declines then cost becomes a more serious consideration to be balanced against the level of that income i.e. can you afford it, and the desire of ownership. As income declines further still there is a point when purchase becomes impossible without serious implications on every day lifestyle. Of course the borderlines can get blurred and at times I expect that the 'rosy glow' of a new expensive rifle can cloud other considerations. So, in the end it all boils down to your personal circumstances and take on the hobby / sport you love.
If you can afford it and want one ... why not? It's your choice.
Me? Spend £2K on a rifle? No.
