I dont have too many regrets honestly. I only collect the figures I love and have been able to snatch up every figure released from the G1 series with the exception of Prowl so I feel really good about my collection. I never paid scalpers prices either, with the exception of the Nemesis but it was like $20 more so no biggie. I guess if I had one regret itd be not getting Metroplex but I feel like his time will come soon.
