ADSL or WiMAX?

[cavedog]

I currently have the 384k ADSL at home. But I have wimax coverage at home. Now Wimax is up to 512k right and the adsl 512k is more expensive.

WiMAX up to 512Kbps Access (access only) R 240.00 p/m



Faster DSL - up to 512kbps (access only) R326.00 p/m


Now which one do you suggest. Do I stay on 384k or should I move to wimax.
