which version
3.0 can be slightly tedious to build with lots of small parts and stickers
origin seems to be simple build but lack the detail of 3.0

Start with HG, HG is beginner friendly and cost alot less than other grades so u dun feel the pain when u inevitably makes a beginner mistake like all of us does and still do from time to time..

Try HGUC RX-78-2 Revive.
