buying 7x7

So I am wanting to buy the PiCube QiYi Warrior 7x7 SE (Core-Magnetic + UV) I know I can afford it considering I have 47 dollars maximum right now. I thought of buying from Miss @Hazel because she has some cubes, but I would like a new 7x7 with these exact specifications. So the cube itself costs...

I was thinking to buy some bigger cubes than normal 3x3 for challenge, so i would maybe buy: 4x4 5x5 6x6 7x7 They don't have to be so high quality, if it got's good condition and stickers are good, I'll consider. Send me PM.
