help me build a straigh razor shaving kit

Hi - I am no stranger to DE shaving but want to take the plunge into straight razor shaving. The only thing I know about this is that there is a thing called straight razor.

Is this a time consuming thing? Does this require too much maintenance? I have many curves on my face...well - more so than usual....would this be a problem? Is shaving with straight razor more time consuming than DE with 3 passes?

Please note for past 3-4 years I have been shaving with DE razor....
