mastering and monitoring solutions

I am being sold on a Lynx Hilo for my mastering conversion and monitoring solution. Do any of you ME's have an opinion on this? I noticed the Aurora has 8 channels (instead of the 2- Hilo) and sells for ~$500 less than the Hilo. Is the conversion the same? I was also looking into the CRane Song HEDD.

Please help, because my head is spinning over this.

Thanks
