Yeah true, TA is the best way to get tickets on. I always got tickets through TA for the Area Tours but for CDL I always had to buy from a reseller store. Itäs really hard to winn a ticket for CDL in the TA lottery. But it's possible.
About the tickets costs in reseller stores. Well it depends on how good seating you want and on what timing you buy your ticket. But for a great seating you might have to pay over 70'000 yen. But you can get a good seating for around 20'000 yen. Once I bought two tickets (one for 30th and one for 31st) with good seating (middle of the arena, not on the floor but close) for about 30'000. But at that time i bought the tickets 1 hour before the 30th show would start.
You guys can also look up the price for a CDL ticket on the site Matthew posted.
