boba is a tough one to start trooping with. a stormie can basically be bought in a big box, and if you can peel and stick velcro, you can get a passable trooper.
with fett, there are so many parts, all sourced from different places. painting, variations on the suit... it's a lot of stuff.
not to mention that most garrisons only allow 1 of each character at big events, so your troopability is limited by how many of that character are in your region.
i always suggest that folks looking to just get out and troop start off with something easier than the "face characters" (boba, vader, jango, zam, etc...)
definitely don't give up on the boba, but it may be worth thinking about something like an imperial officer or technician type costume to get your foot in the door.
