i won't say do v3 or v4.right now there are a lot more things(characters,clothes etc.) for v3 that were practically non exsistent say a year ago as i began to learn 3d. at the present pace as g4 figures are released 6 months or more from now v3 will become rarer to find. but just as with v2 or m2 still some thing people will work with.at the moment it seems v3 may be at the pinnacle of her career.i think it would be safe to continue working with her .but still keep future gen 4 characters in mind.
