Whats the best compressor(s) for me to run?

I have a 96 eclipse with strut bags, and im running a viair 450 compressor with a 5 gallon tank. i barely have enough air to raise it one time, and i want 2 compressors, i just want to know what everyone thinks the best compressors are? And should i go with 2 tanks and 2 compressors or 1 tank and 2 compressors??
