Serious Question Why Should I buy

Looking for valid opions please, I have been gaming for a little over 1 1/2 years now. Since that time the system rack continues to expand. I started with a gamecube I did not get into it. Then a Friend game me a PS2 I was hooked I played that for several months until I went to his house and saw his PS3. I bought one and loved it. My wife wanted a Wii so we bought one "Which we have used twice". Now I am looking around and thinking did I miss something with the Xbox, I have seen some Xbox titles I really want to play "Gears / Fable 2 and left for dead". But My question is ... Should I invest in another system would I get the benefit out of it. I keep on hearing about the people having to buy another xbox because there old one crashed, dirty disc errors , Loud drives. I am not picking on xbox I just looking for some good information. Plus is it true they charge for there online service? Also I am so used to the Playstion controller, do you know if there is a converted plug?

Then the last question "yes I am a cheap gamer, have to be in these days" which one should I buy and whats a good price.

I think I am going to wait till maybe the new year, see if I can snag a deal right now the cheapest I can find is Xbox Pro system with a 60GB hard drive for $140.00 at the best buy Auction site.
