I would buy it if the price is right.
I have literally FOUR jobs right now that I could use it for.
One job we are using our 17' Little Giant ladder, but it would have been easier, faster, and safer to use a bucket truck to complete.
The second job we need to rent a tow behind. Actually, we should be there right now, but because we used ladders on the install yesterday, it took longer than I planned and we couldn't finish, so they are finishing up the install from yesterday right now, and won't be able to do the one planned for today until next week.
The third job I told the guy we can't install, and he claims he can reach with a ladder, so he's going to install it himself.
The fourth job I haven't even quoted, since the install is going to be as much as the sign, and its for a good friend, so I feel like a jerk saying "oh yeah, the little banner you want is $350, but I have to rent a lift, so its going to cost about the same amount to install it.
Anyway, there is no one dependable around me that has a bucket truck. We've been screwed over by two different "sign maintenance guys" with bucket trucks (who weren't cheap or anything either.) And the only other person who has one is always very busy and charges A LOT. Like, an insane amount to do anything. Change one face? That will be $400 please. For driving 10 minutes from his home and taking 30 minutes to swap out a piece of acrylic. IDK.
I'd say go for it, and make sure other local sign companies know you have it and are available for installs.
