Try an experiment:
Go in to a Lowe's or Home Depot, and look at the cabinets there; pull out a drawer and open a door.
You will see the difference.
Then, if you say that that doesn't matter to you; then go ahead and re-face.
The other question is; would you be doing this for yourself, or the next owner?
If your thinking about the next owner, ask this question; "will they want a cheap half-a-- job?"
