I used to run the rivers around here in a small underpowered jet boat that was always a disappointment when the power was needed or when ability to safely jam a rock was a necessity. I took excellent care of it, ran it for ten years, and lost about 5-6 thousand overall when I sold it.
Now I have a heavy duty boat with more than enough power to get me in trouble, it is bigger, safer, and capable of moving rocks out of the way when needed without fear of it becoming a large chunk of scrap aluminum. I will run it ten years (half way there now) and lose probably 5-6 thousand when I sell it based on current prices even in this economy.
Get the good stuff. everything depreciates, would you rather lose the money on a peice of top of the line equipment or on a third rate bargain?
