I always advise it depends on what state the rest of the bat is in. If it's in decent nick, then it's worth the cost (I charge £60 currently plus postage), if not then it maybe isn't and you could just see use it until it snaps.
Not all handles are equal, so I would just ensure you use someone who uses good quality handles. I use the same ones for rehandles that I use in all my own brand bats, which I've not had any issues with. However, I've been sent some from suppliers I would only use as firewood! 😆
Most should come with a full refurb, mine includes stickers (if needed), PU toe guard, scuff, grip etc
