My expensive Fasco pin nailer is kaput. The piston is bent, and needs to be replaced.
So I borrowed my neighbors Harbor Freight pin nailer.
I really liked this HF tool - it leaves a tiny hole. The Fasco nailer leaves a noticeably larger hole.

A replacement piston for the Fasco is $28 plus tax etc, a new HF nailer is $27.

I'm tempted to retire the Fasco and get a HF nailer. But I can hear my mother giving out about the throw-away society!

I normally like to get tools repaired (or do it myself) but I'm disappointed that this happened to the Fasco (I've no idea when or how) and I've always been disappointed the hole is so big in comparison to other pin nailers I've used.
What would you do?
