I just bought an 18 1000 5 LE OTD below $19k.
They are identical to the 19 except for color.
The dealer had a 17 LE 1000 3 that I originally was going to buy, low $15, but got talked into the 5.
Any of the three will be great rigs. Depreciation is a small factor for a toy.
Make the deal on the one you want and enjoy.
