If your DM starts using a LOT of components, just start buying truckloads of Primal Essence. Costs x1.5, but it works for any and all spells.
If your DM allows it, buy a Focus Component at x50 cost. Combine the two options to need just one focus. A very expensive focus, but still. My 13th level Sorcerer has one at 11,250 gold.
