Dune is faster -- and cheaper. Paid $5,000 American for my 2012 TI at the Seattle Boat Show in January. Was going to buy one anyway, so I took advantage of the show price. I think they normally sold it for $250 more than that.
You might find boat shows in your area with similar discounts. That was the boat only price. But they also offered 10% off any accessories purchased within a certain time period.
I also bought a TrailX trailer. I'd do so again in a heartbeat, even though in my opinion it needed some modification. Being aluminum it is light weight and corrosion resistant. It is sturdy and well made and their tech support is excellent and prompt. If you do go the TrailX route, I have 2 suggestions:
1) Do not get the SUT-350-AIT recommended for the TI by Hobie, because it is not long enough to store the TI. The back end hangs off 4 to 6 feet. Sun-E-Sailor on this forum has a recent posting about one with a longer tongue that he put 3 cross bars and cradles on. It is the SUT-350-S
2) With either the SUT-350-AIT or the SUT-350-S, I recommend lowering the tongue (and thus the boat) by moving the tongue from above the frame to under the frame. This modification will allow you to float the boat back on the trailer rather than lift it on. That is a huge benefit for those of us with problem backs.
