If you KNOW you need all the components, then yes.
By the time you add the cost of the individual components, you will spend more than you would on the Kirbans unit. And a 'pro' is that the Kirbans unit has a lifetime warranty. Best deal going to my knowledge. I believe GBodyparts.com sells the same unit.
The only 'con' I know of about the Kirbans unit is that (IMO) the motors are not "rebuilt". I have see 2 of his units now and have questioned the motor on both of them. They look like they were cleaned and painted. They tested out fine at installation and are still in operation today, so they can't be all bad. They didn't test any different than my P/M that hasn't failed since I rebuilt it back when parts were cheap. Hanks motor was the most expensive part then.
I spoke with Hank back when I got my motor and he had informed me that these motor/pumps cannot be "rebuilt". I wouldn't know any different. I gave up trying to get my old motor apart to see how it was made.
That's my knowledge. Hope it helps.
