No gold, the guy above, has also stolen a few good rifles that should have been mine,,, had I just got there before him,,,, so watch your Friends!
Another thing, study the types of guns made, and decide just what you like and want in a rifle or pistol. Rifles without patchboxes generally sell for less than those that have one, so if you decide you like the look of a box on a gun, don't buy one without one just because it's inexpensive. Saving your money and finding a gun with a nice patchbox on it will make you a lot happier with your purchase in the long run.
Putting an ad here might work out well also. I'm sure there are guys here, myself included, that have a few inexpensive rifles hanging around. Those guns might not be in pristine condition, so it would depend on what you're looking for, but making your wants known is a good first step.
Generally speaking, the fancier the gun the higher the price. Guns in fine condition are worth more than lesser grades. Signed with a makers name adds a bit, signed with a well known maker name brings more, and signed with a Great makers name even more yet.
Realistically it's easy to spend 25/30 thousand on a good rifle, but a big name dealer that I know has said many times that he makes most of his sales on guns in the 2 to 3 thousand dollar range. There's literally thousands of rifles out there in this price range,,, you just need to get hooked up with them,,,, preferably before your Friend does.
Look through the Library here and try to make a mental list of the attributes that you like. When you have questions, just ask here, or PM any of the collectors here and I'm sure you'll get your answers.
