Yes Adventure, what you are talking about is called "shill bidding" and against ebay rules. If I feel that something is going way higher than it should, I simply do a search by the bidder I believe is doing the shill bidding. If I see that that person has only been bidding on that seller, I don't bid on that auction. Of course nowadays it's fairly easy to create new accounts each day, so you just never know. The downside to shill bidding is, if the shill bidder ends up winning the auction they are obviously stuck with their own item and seller and buyer fees. That is why it's much better to have a reserve on your item or you can start it at the lowest amount you're willing to let it go for. The only thing about reserves is that it really turns a lot of people away from your auction, since many people don't like wasting their time on a mystery amount.
Be, it has always been that way since the day I first started buying on ebay. I think you did well for your first auction, I remember mine didn't go so well. lol You get so caught up in the bidding when someone outbids you in the last minute but common sense kicked in on my second and it's good to set yourself an amount you are not willing to go over. If you do not want to sit there until the very last minute of the auction there are these programs that do the bidding for you. These programs are called "snipping" and completely legal in Ebay; though many buyers and sellers don't think it's fair. How it works is, you go to the website that offers you bid snipping(some you pay for, some are free), you enter your ebay information and you enter the highest amount you are willing to pay for. The programs waits literally until the last 5 seconds to bid, that way if your bid is the highest, the other bidders will not have enough time to outbid you. So you can see why a lot of people may not like it but I must admit I've used it myself to try and get the best deal and not have to stay up till 3 am for an auction.
Good luck Be, if you have anymore questions just let us know!
