need to replace a door handle/lock set. lowes/home depot? somewhere local?

I typically just go to HD or Lowes and pick one up...be prepared to shell out some cash, as the decent ones are a lot more expensive than you would think.

Kind of like gun safes, the ones you can pick up at a big box store can be picked and broken into in far less time than you can imagine, but most theives aren't picking locks.

I have Schlage from Lowes FWIW.

I recommend Schlage or Baldwin but any lock from the big box is fine because locks only keep honest people out.
