Obviously an emotional topic...
At least for some of the posters. I can't, and won't begin to try and quote numbers exactly, but consider that Gary Kleck's data, now widely recognised, is that guns are used for defense close to 2 MILLION times a year in this country! Now, it appears that nowhere near all those times is the bad guy shot and/or killed (where are all the bodies?), so it seems reasonable to me to assume that guns are not fired in defense more than they are fired.
SO, if the question is "a cheap gun, or no gun" (and it is), for me, I go with the cheap gun everytime. For personal defense. A cheap gun you have on you is worth more than a high quality gun you don't! Especially if you can end the situation without firing it!
Absolute worst case scenario, homicidal psycho who will not be stopped by anything less than physical incapacitation, a cheap gun is still better than no gun! But a good gun is better yet!
Like the man said, if my life, that of my loved ones, or even my property, hangs in the balance, I'll take a slim over none anyday.
Since I have good guns, other than as intellectual exercise, the point is moot anyway.
