I have previously had my praestantia and pod refurbished and it was around £35 or even less, new stickers, sanding, oil, sheet and a grip. It comes back looking like new. this was a couple of seasons ago so dont know if the prices have changed.
If you do have slight repairs i.e. small cracks or indentations they will fix in the same price. I had a slight crack on the toe i was worried about and they repaired then taped with linen cloth and covered in pva, makes it very durable. never had a problem with the toe again.
great service
