Is there any secure way of getting good tickets without going through resellers? I really want A block tickets when I go but don't want to take a gamble by waiting until I am out there or paying over the odds for them either.

¥75000 is almost £400...my flight will cost around £800, if immels estimates hold up, probably another £800 for accommodation/food, and easily another £1000 on shopping/ other stuff I will do there. £3000 is a years university tuition!!! *faints*
