My M600 is the blue/gold version. But I think the blue binde looks much, much better with Rhodium trim.
Yes, they breed. You'll start saying "Well, that M200 Special Edition color looks nice, I should get one before they go out of production," and "Everyone talks about an M800, I wonder what's so great about it?" And pretty soon you'll have both.
Then you'll need an M400 to complete the set. Then you'll say "That Anthracite grey looks amazing....." and "Someday, I'll want a flagship pen. The M1000 shows up on Massdrop sometimes at a pretty good discount...."
Yeah, that's kinda what happened with me (only I don't get the larger pens -- M200s and M400s are a better size and weight for me). The new White Transparent M600 was surprisingly light, compared with my experience with other M600s (someone in my local pen club just got one) -- but seeing the pen in person sort of dimmed my desire for one somehow; it's a pretty enough pen, but didn't grab me the way some other birds did.
And yeah, I was one of the people saying "That Anthracite grey looks amazing...." Back when they came out with the M805 size a couple of years ago, I was going "Man, if they made that in an M400 size I'd be knocking over banks to pay for one...." And then they did, and fortunately I didn't have to resort to a life of crime. For it OR the M205 Striated Blue. Although it was a little startling to get a phone call from PayPal asking if it was a legitimate charge to my account -- given the price for the two pens, and that the payment was going to Europe.... ["Uh... why yes, yes it is, thanks for calling...."]
I still have way more vintage Parkers -- but my modern and modern-ish Pelikans are my most expensive pens (well, except for the 1950s 400 with its OB nib -- it's right up there, too... ).
