The Music Source (TMS - see Suppliers sticky) carries Mackie, and that means they carry the Onyx series of FW mixers. I've also seen some Alesis products at TMS so it's possible they have the Alesis FW mixers. Alesis is also distributed by Avesco; 5th Ave is their retail outlet in most commercial centers (Quad and SM North carpark are known branches). JB should be carrying the M-Audio NRV-10 by now, if not, try asking their branch managers for availability.
