After returning the International Violin Mandolin Kit, I made the decision to go with the Stewart MacDonald Campfire Mandolin Kit. This flat top mandolin design is based on the Gibson Army/Navy Mandolin that was made briefly during WWI and sold only in the PX to soldiers and sailors. 1917- maybe 1919. There was also a Gibson Alrite model that had more ornamentation. These are all valuable today. Martin also made a very nice flat-top for a time. This "pancake" mandolin style lends itself more to Celtic music than Bluegrass, and that works well for me. If you are interested in this style mandolin but are not the "build it yourself" type, then I recommend taking a look at the Traveller mandolins built by Steve Smith, or Big Muddy (formerly Mid Missouri) Mandolins. These are some fine crafted all-wood mandolins.
As you can see from the picture, the Stew-Mac Kit leaves more to do yourself. I am hoping to end up with a nut width that is wider than the standard 1 1/8" . Maybe 1 1/4" would be nice.
