Like trigg I have the older model head hunter a buddy of mine just bought the head hunter 2 that I think they started making in 09? I like it a lot. If it wasn't for the low water bridges on the nfow where I mainly fish I would own a low side or the clacka eddy. Ro has some pretty cool new layouts but they are expensive and I have always wanted to row an adipose but again they aren't cheap.
I bought my boat from mountain driftboats and they are good people very similar to buying a used boat from one of the manufacturers it is refurbished and usually has a new trailer and oars. Most of their used boats are a couple year old guide trade ins. Buy a refurbished used boat from on of the manufacturers or dealers is your best bang for the buck IMO like trigg said you will save a couple two or three grand and get a like new boat. The main thing is you will have to be patient to get what you want.
It's hard to figure out exactly what you want if you haven't spent much time in a driftboat but they all basically get the job done. I wish I had gotten a galvanized trailer, walk around floor plan and something with better rod storage. Besides the cost of the boat you will likely spend some money on upgrades and to have it shipped to you I spent around 1k extra on mine I think 600 of that was shipping.
