Turbochargers are driven by exhaust gasses, whereas a supercharger is typically driven by the drive belt. Due to this design, the turbo has a lag time, where it waits for the exhaust to spool up, but can have a higher top end. Superchargers have a more linear effect, as they are parallel to engine speed, so they are better in the low end. Due to the heating of turbochargers by the exhaust gasses, many require engine coolant to be pumped through them. Also an intercooler is pretty much required in a turbo application unless you want a case of the knocks.
Pricing really depends on your application, search around on here and see what people are doing for their setups. Depending on the device, supercharger can be a single unit to bolt on (which can be expensive depending on complexity). But with a turbo, there is a lot of piping, and if you have the means to fabricate, you can save money by making your own instead of getting a kit.
Maintenance:
Frequent oil changes, and make sure it's quality stuff. With the amount of heat going through a turbo, it can burn dirty oil and stop your oil flow, which is very bad.
