Eh, the money is better spent on a quality snare or kit. MIJ's look neat .. until you play them! :)
At one level, I have to disagree. My first kit was a LaBoz MIJ in the mid/late 60's. I never had any serious difficulty tuning it. The rail setup wasn't great, as Kenwood has also mentioned in the past. I also had a Stewart in the 90's that was the same in sizes as this Capitan kit and it sounded very good without any modifications. As I recall it, the only variance would have been the wrap and badges, though I'm not sure it had a center ring in the bass drum. The LaBoz did have that feature. I think it depended on what company built the drums and into what price range they were selling them.
The point Mark makes about hard to find parts is definitely an issue if you want to put the kit back to as good and correct condition as possible it will be a treasure hunt and might not be inexpensive.
