I sort of want everything. But I just realised that I don't really like everything.
First, unless it's a very iconic character that I love very much, I don't like G1. I traded lately a complete Doubledealer plus a MIB Seacon reissue box set for around 300$ worth of Bayformers from 2007. No regrets at all because all of these figures are awesome.
One regret is the Power Core Combiners. I bought a couples because they were on clearance but I found out at least ¾ of them SUCK. As scouts, they are not really good, mainly because of the default tiny derpy head and the sacrifices made to make a torso mode. Also, their blue bits are pretty ugly. Most drones are garbage looking.
Another mistake is DotM HA Leadfoot. You see, I always wanted him, but I did not want to pay 60$ for him with shipping. He is a USA Target Exclusive after all. Then, one day, finally see him in Québec in some obscure Toy Clearance Shop on the side of a highway.
I was overexited to see so many so cheap so...... I bought 7 of them... You know, for trade and selling.

DotM HA Leadfoot is an EXCELLENT TRANSFORMERS. Still, 7 of them is way too much. Especially when he is sold for cheap even on Ebay. I should have only bought 2. One to open and one to keep sealed. Anyone wanna buy the other five?
Jeez, I think I'll be stuck with them for a loooooooong time.
