If you feel you must get a new cutter, any of the ones mentioned are fantastic and you will be very happy with their use. I use both the Xikar and Palio.
In light of your question...
The big question is would It be worth upgrading to a 40 to 60 dollar cutter and is it worth it.. Help BOTL??
... I'd have to offer my opinion that it is not worth it. I have come to the conclusion that we spend far more on accessories than is necessary. Any simple razor cut that scores the cap off will work perfectly (for Parejos).
It is just my opinion that we get too caught up in fancy lighters and fancy cutters. Good cigars and good cigar storage is what matters most. Yes, I am a hypocrite. I also have fancy lighters and fancy cutters. So, while I think it would be a great Christmas present to yourself, I am just saying that it is not necessary and if you do get one of the three, you don't need to purchase all three of them.
Go with Mark's "Cigarmony" if you make the purchase. When you never ever hear one negative thing about a company, that's where you wanna send your hard earned $$$ to.
