Do it! (I need the company lol)
I have some figures with real hair. Some I've haired myself. Honestly there's not much upkeep but I don't move around on my figures too much. I usually find a pose I like and it'll stay that way for a good while. But even when I do repose, the futzing is very minimal to get to where I'm happy with it.
But as you've mentioned if this isn't a line or franchise you normally collect I don't know if you'd really need to go all in or even start. I feel like the passion for this level of quality should reflect the passion you have for the subject matter.
But also. If you do buy and decide its not your thing you'll have absolutely no problem selling and making a profit off it once these have sold out.
Well since I'd be going with sculpted I have until February 3rd to come to a decision. I allowed that latest Gandalf preorder window to come and go so I guess I would be doing as a few people said - just having the trio of Aragorn, Legolas and Gimli........and Borom- NO, DAMMIT!!!
