I'm not one to tell you how you spend your money or display your figures but I just wanted to give some insight. Vegeta is coming out relatively soon, you'd be better off saving your money and getting an official one. Trunks is also coming up as well. SSJ Goku is re-releasing every other day and is very affordable, so there's no need to feed Datong your money when it can go to Tamashii. Same goes for Normal Goku. He is still in a not so crazy price range for under $80, I've seen plenty of $60-$70 ones. Add in the upcoming releases and the recent ones that are still near retail, most of the figures are not so expensive. As for every other figure like the villains or SDCC's, there aren't any bootlegs available (thankfully), except maybe Scouter Vegeta or Arlian. Those if you really want em, unfortunately, you just gotta pay the hefty price. The Androids I really doubt will get any kind of re-release or repaint since they weren't exactly flying off the shelves.
If you can, you should really try to stay official. Bootlegs can be great for custom fodder, filling in gaps for REALLY expensive figures, but if they can be avoided, they should. It's just kinda sad when you see collections that are 80% bootleg figures. Just my 2 cents, again no disrespect or anything, just some insight from one collector to another
