I bought a small compressor with a tank. The compressor was excellent quality but the hose and cartridge that came with it were cheap. The cartridge that came with it didn't fit the tires very well and the small valve inside sometimes didn't seat all the way so there was a lot of leakage, both from the valve stem and from the cartridge itself. This one is durable and doesn't leak. It fits very well on the tire's valve stem and the leak is almost completely gone. With the exception of one cartridge that actually clamps the lava wand, I don't think you could do better.
