At one inch, I'd get the set redone if you're a serious player.
$29 is a decent price for all of that - I assume the shaft is the typical DGS300. I would also have them adjust loft while adjusting lie.
However, and there is always a "however," you may not get the consistency you want in terms of specs between clubs by the typical OEM. They generally do not spine/flo or go for frequency consistency between shafts, and do not give you a large choice of shafts.
If you are keeping those irons and playing competitively, I would go to a reputable professional club maker for a fitting, shaft selection, and rebuild. You will, however, pay more than $29 for a professional club maker to get a quality rebuild.
