I had an old Koffler that I bought for $2500 then sold it 4 years later for the same amount so I would say that the resale held up on that boat. I would also say that the Koffler is far superior to the Alumawelds or the Fishrites. It tracked really well and took a beating (that thing was built like a tank). I have rowed Fishrites and I have yet to see one that tracked well. In fact a friend on mine had one that came from the factory twisted. The Alumawelds track OK, but they dent easily. I have a Wild Hair now. That thing has got all the comforts of home and responds really well. In fact my only complaint is that it responds so well it is a little twitchy while pulling plugs. It has a super light feel when you are rowing it and rides really high in the water.
I don't have any expereince any of other brands mentioned. Here is how I would rate the boats that I have expereince with.
*Wild Hair (Lots of features, rows and handles well)
*Koffler (built really tough, they track straight, they row pretty well but the handling is a bit sluggish)
*Alumaweld (Nice features track straight, they row OK, but dent easily)
*Fishrite (they row like tanks and don't track straight)
*Lavro (The boat I rowed was an older model so it may not be a fair comparison. It rowed a bit on the sluggish side)
