You have no chance of installing a graphics card in an A1200; the only option is a BVision graphics card which needs a BPPC board. Otherwise you need to tower the A1200 to use Zorro cards.
Therefore, your only option is to get a scandoubler/flickerfixer (which you apparently aren't going to do) or a suitable monitor.
A shame you are in the US. Have a prefectly good working C= 1960 monitor right here that is doing nothing, but it's local pickup only...
