I'm a vintage G1 purist but I don't mind buying a revamped G1 original with minty fresh repro labels - but I won't go out and buy those sheets myself.

Having said that, I believe these labels do add value to a figure (especially fort max). I mean, if you think about it, comparing two mint figures; one with brand new stickers and the other without - I'd say most people would choose the one that looks more appealing on display.

Though like orion said, this may put off a few g1 collectors who despise repro in any form.

Reprolabel prices sorta suck as well. I got my stickerless complete metroplex for $50, but I'm not gona pay another $26US for those labels.

So at the end of the day - I'd say value can be increased, but only if the price is right for the figure you're upgrading.

[edit] I've also noticed repro stickers can be cheaper on ebay
