When I damaged my solid roller (too short pushrod, broke an adjuster, chucked one lifter out, other went sideways), I had it reground. I lost quite a bit of lift, added unwanted duration, but it cost about a quarter of what a new billet roller would have cost, and still ran quite well. They did the best they could with the damaged lobe, so I have no complaints.
Cost for a regrind will depend on if you have a core or not, whether cores are fairly common, what kind of grind you want, and who is doing it.
What's nice about rollers, you can change cams and re-use the lifters (if they are still in good shape) something you can't do with a flat tappet.
