Figures were generally around 7-9k those many years ago. More expensive figures did exist (such as 1/4 scale ones), and they were usually around 12-14k, which seemed expensive at the time. Some smaller scaled figures were priced around this too, but they were often extremely intricate. Take, for example, Saber and her bike.
She retailed for 14k, but given the detail on her, would easily go for probably 18k these days (if not more). Keep in mind all of these prices are before store discounts, so they would be even cheaper at stores such as AmiAmi. This Saber was only a little over 10k with the discount.
Basically, 5+ years ago, spending over 10k for a figure was pretty rare, unless it was considered one of those "exhibit pieces". Nowadays, we're lucky to have a 1/8 scale figure be 10k, let alone the 1/7 scale (and larger) ones. The golden age is indeed gone, but I guess it can't last forever.
