I'm pretty sure the OP was asking for a Wall-E that's scale with his Transformers. Hence the picture and the need to tell us he blew his money on TF:A figures.
Unless he wants a giant Wall-E as a mobile base for his Transformers, U-Repair is the best one IN THAT SCALE. It also has the best articulation out of any of the Wall-E figures on any scale, and has the best accessories. Plus the Search and Protect EVE, which is the best EVE, is scale with U-Repair Wall-E.
Giant Wall-E sounds pretty badass, though.
