If you're just starting to learn to play the guitar, the instrument you buy can make a world of difference in the progress that you make in playing. Never let *just* the price be the deciding factor
when you make your purchase. Although it will probably play a big part in determining which guitar you can buy.
Usually your money can buy the most guitar if you find a quality used instrument. If you're not sure exactly what to look for (or look out for), take a friend or someone you know that is knowledgeable on
the subject. It's always better to be safe than to purchase an instrument that may require extensive repair after you've spent your money.
There are many fantastic deals to be had buying at auction. One of the first things you should do before placing a bid, should you decide to, is to email the seller and ask him or her if there is ANYTHING at all wrong with the instrument (that isn't listed). I've found that sometimes a seller might not list something that he/she doesn't consider a real big deal (or maybe does), but when asked specifically, they won't lie about the state of the guitar.
Obviously you're buying a used instrument and it's usually not realistic to expect something in perfect condition, unless it's a very high dollar piece. You're probably not going to spend that kind of money on your first guitar however.
Try and get the approximate age of the guitar, find out if the seller purchased the guitar new or used. Ask why the guitar is being sold. Even though you won't be actually checking the guitar out in person, it's still advisable to have someone that has some knowledge have a look at the auction that you're interested in and give you their advice.
So, you've got a little more to work with in selecting a guitar to bid on at auction. Please have a look at the listings on this site. Nearly all major manufacturers are listed, and you can also get listings based on price. There should be more than a few good guitars that would be right for you. Good luck.
