Well, no harm in trying. If anything happens you'll get your money back anyway (fingers crossed)
I did get a YF-29 30th Anniversary for $110 on Amazon so I'm damn happy with that (THINK its new, didn't transform to check joints)

Cheap one has appeared. Go get it
Same situation as you and it hurts to not see them pretty birds. I have Valks beings shipped abroad and I dread the idea of hauling things back home... half way across the globe...
I think a Roy 30 would be a hard sell since the most logical change would just be the red stripes replaced with yellow. That change would be too small and make a lot of people call them out for repainting something so tiny. Ozma on the other hand would just create PO hell...
If it really bothers you its possible to get rid of it by sanding down the said part with really fine steel wool or sand paper. One you've done that you will have to clean it up with a buffer. To be safe you'll also have to mask off the parts will run through the buffer to avoid polishing off any unwanted parts. Alot of work for sure :X
Micro fiber wipe if you wanna be 100% safe.
EDIT: I wonder if the 171 armor parts would be worth it as an add-on (will get the 171 one day... one day...)
