It does seem rather high for a one-trick pony. Look at what you get with Photoshop (full) for about the same money. That app isn't geared towards the home market either. The other fact is that the trees are just an incidental part of the image for archicetural drawings anyway. Does anybody really want their customer to focus on how good the trees look? I suppose it all depends on your style. I do belive that they'd sell many more copies if it was priced right.
