Let's see, in my current inventory I have the following:
1 American-made revolver (S&W)
1 American-made rimfire carbine (Ruger)
1 English-made centerfire carbine (Enfield)
1 Japanese-made shotgun (Browning)
Next on the to-be-acquired list is a Czech centerfire rifle (CZ).
So, I suppose my ratio is 1:1 at the moment, but soon to change.
I don't get too hung up about buying American. I try to when I can, but my gun purchases tend to be influenced more by cost, utility, and desire rather than political motivations. If I'm going to buy all-American all the time, I'd better stop buying gasoline and trade in that Toyota I just bought (show me a reliable compact American car that gets 41 mpg on the highway, and I might be interested).
I do know there are certain things I prefer not to buy for ideological reasons, no matter how much I might like them. I won't buy anything covered with Nazi markings - just too much bad mojo to sit well with me. Likewise with Arisakas and Mosins. I'm not saying this to pass judgement on anybody who does own these items, it's just not for me.
I used to own a Yugoslavian SKS. I sold it mainly because it didn't fit me right (bad ergonomics). However, I never could shake the feeling that it may have been used for some untoward purposes within its native land. Additionally, when my brother returned from Iraq and I showed it to him, he made the comment that he'd seen some of these ... from the opposite end.
That pretty much ruined any enjoyment I derived from it from then on.
