Giving up photography just because you don't have access to the 10D? Have you considered using a film SLR? A decent 2nd hand one(e.g EOS50+grip <$500) doesn't cost much and is more than adequate for your purpose of shooting sports events.
FYI, I use a 13year old Minolta SLR for martial arts tournements and its rather adequate.
Other times I use my 602, which is also more rather competent in that area. You don't necessarily require a 10D you know?
Guess you should just take a step back and think of whether your interest lies in photography or the equipment.
