I agree with Naldo, have experienced both (though limited time on Top Spin- because I don't own an X-Box), but Smash Court Tennis is just so much more realistic! Besides X-Boxes are lame
, you will get much more enjoyment/good games on the PS2. If the repairs are looking like costing a lot, you could always replace your PS2, the retail price has dropped a lot, so it's quite inexpensive to buy now ( similar cost to the X-Box anyway!).
