Picked up attacktix Omega Sentinel today for the princely sun of 99 cents!

I've been looking for this bad boy for quite a while. It came without the four missiles but luckily Omnicon/decepticlone/minicon missiles fit it. Love the machine gun firing action. It has only 4 tix of movement compared to Omega Supreme's 8-10 (can't remember the number), but at least this one has ranged attack. When we've played Omega Supreme always gets wiped out early. He's a big target that everyone goes for.
My kids are clamoring for an attacktix brawl now.
And I'm tempted to repaint Omega Sentinel into G1 Omega Supreme.
