Hmmm, as long as you don't go into deubt, you should be fine ;)
Most of the ROTS sabers are pretty cheap, so its up to you which one you want ;)
EDIT: I just found a sidious ROTS saber for $219.00 but it now, a Yoda ROTS for $250 buy it now, an Obi-Wan ROTS for $240 and a Darth Vader ROTS for $200 buy it now :o
