I really enjoy third party add-ons that enhance figures I already own. There have certainly been plenty of companies over the years that pad out their sets with questionable/unnecessary parts (really looking in your direction, DNA!), but mostly, I find that I enjoy the sets that I do buy. I very rarely order Reprolables anymore, unless it's for a G1 figure or if I think that I am going to use most of what the sticker set comes with. By the time you figure in shipping, what should be just a fun little add-on costs about as much as the figure itself, and I don't want to go down that road.
DNA's Ark set was really nice though, and like Undead Scottsman mentioned, it did not sting as badly knowing that it didn't bump up against the cost of the Ark itself. I do wish though, that companies like DNA would make some of their items a la carte, such as guns, "gap fillers", etc. That way, if a customer wanted just the gun from a "set", they wouldn't have to shell out the full price for a bunch of stuff that wouldn't get used. This happens from time to time these days, but I'd like to see it more.
