When i go into a shop the sellers are talking that fast and that much, when i realize that this guy has really strange shoes, he is 5 sentences further and i leave the shop with a remote controlled alarm clock, so its much better for me to get advice here.
The Montana is unfortunately much to expensive for me, i saw the picture comparison between the 35t, the oregon and the montana.
When i want to compare sizes or help my imagination, i take a double meter stick and look at the size there, helps also. When the oregon and the 35t are the same inside and just the screen of the oregon is bigger i would take the oregon.
