[Unanswered]  Beyblade Plastics Lot Pricing

So, there's a friend I know that has a roommate that's a retired blader, and he has a couple Plastic beys that look like they came out of a junkyard with the parts layout and a really cool Dranzer V2 RC Launcher. I think one of them is a Dranzer S that's missing a Bit Chip and has an Eight Heavy WD, a NEO Right SG with a South Magnecore and the Spiral Change Base, and a Dranzer V2 with a Ten Balance WD, and Driger F's Full Auto Clutch setup. I know these are pretty bad, but it's more to just have and battle with for farts and grins. Any idea on a good pricing? I'm hoping to make the guy an offer. Any help would be appreciated.
I would differently buy them just cause there rare now a days
