DOT 4 brake fluid. Check fluid level. Don't worry about prices until you determine if fluid is OK. Hand brake or brake fluid float make light come on, so wiggle handle and check fluid level. If you are missing fluid frequently, it is leaking somewhere, and that usually is the calipers....
If you don't have an owners manual, you can download that and the full set of factory tech manuals, called the RAVE, at link below.
If fluid is low, does that mean you have not checked that fluid recently? How about your other fluids? Once a week is all it takes, beats getting stranded, blowing a head gasket, etc.
