Three that I really enjoy are A Scottish Christmas with Bonnie Rideout, Maggie Sansone, and Al Petteway; Christmas Celtic which believe it or not is REALLY good and I picked it up at one of those kiosks at a discount store where you can push a button and listen to a snippet before you buy; also, Yuletide Guitars put out by NorthSound.

Our own Caroline and Sandy Paton have a wonderful one, 'Twas On a Night Like This A CHRISTMAS LEGACY, which you can sample at Folk Legacy.

Also, there are a couple of Christmas CDs at Green Linnet's LISTEN site where you can listen to the whole CD before buying. I highly recommend the one by Noëls Celtiques from Brittany.
