Planet Virtual Boy

Probably i'm gonna get this games: Space Squash, Nester's Funky Bowling and 3D Tetris. How much do you think i need to pay for this 3?

Do you want them loose or boxed?
Boxed and complete in good condition, I'd say you can sometimes get Space Squash/Nester's for about $60 each, and 3D Tetris for around $80.

Somebody correct me if I'm wrong, I'm not all too keen on current pricing.

Thank you! Tthat's was i as thinking to pay but i need to compare.
