I don't really have anything for 24k, but if you find 30k, I could sell you the colourful Zac head. If you wanna pay 40k, then you can go for the other Zac head, and if you have 50k to spend on a head, then go for the GraphtiC or the Tengo head.
For 20k, you can either buy the head by me, or the Lwafflez one.
