So far, my experience with Van's has been rather pleasant. The people at sales have been helpful, crating and shipping was prompt, and the empennage kit arrived very nicely packed without any discernible damage.
It took me about 3 hours to inventory everything. Everything was clearly tagged, and the included materials list was easy to follow. I had a few items that were marked as b/o (backorder), and I assume they will arrive in the mail shortly. None of the backordered items are needed for the initial steps, so this isn't a hindrance at all.
