Lens Help?

[Julian5]

So I am an avid aeroplane spotter and have always used my default 18-105mm lens with my Nikon D3200, For long range pics at the airport though with distances in excess of 3km the digital cropping is not enough. I am trying to buy a lens but I am not really sure what to expect or how they perform, I normally shoot in broad daylight and don't care much about "bokeh". I also use autofocus for fast moving situations and the default Nikon 18-55 lenses seem really slow.

I have a very very tight budget of 150-200€ MAX and I am looking for used 300mm lenses.

Here are a couple I have found on a Spanish used item website that  I can probably reduce the price on.
