Like mentioned above, determine what the maximum amount of money you are willing to pay on a certain auction and stick with it. This is what I do and have won 74 vinyls as a result of this. If an auction (in my case, a record) is initially set at $2.00, then I usually enter my bid at $12.00-$14.00. This gives me plenty of room to win the auction.

Always bid at the last second, so log in to eBay about 15 min before the auction is set to end and keep refreshing the page every few minutes. Then, once it gets down to about 1:30, place your bid. Many of the people who try to outbid me seem to be eBay illiterate. They will place their max bid at say, $3.50 or $4.00. Your high bid will of course out bid them and if they keep pussy bidding like they do, they will never out bid you in time. If the price gets too high though, just back off and let it go. I bet that DJ equipment would be more competitive than vinyls are, but the same still applies.

Also, look at the seller's feedback, their payment methods, and what country you are buying from. The most important thing, however, is to watch your time. There is nothing more frustrating than missing an auction because you were a few minutes late to check the auction status.
