Um, yeah I think so. I mainly have ML in my collection with only a few of the Select figures but while they may not be (usually) as articulated as their 6" counterparts, the Select figures are really nicely done and can (some of them) fit in with the smaller legends line. Here's an example:
My Marvel Legends Cyclops with Select Juggernaut and Colossus
Also, what Wolverine12 said, it's basically what you want to collect. There are some really nice Marvel Select figures and like he mentioned, the Select Rogue just came out, so she's much more affordable than the Marvel Legends one but it's also going to depend on what era you want to collect as well. Select has some of the 90's era X-Men and they're all still pretty affordable (Except Nightcrawer from what I've seen) but the Marvel Legends X-Men have a wider range of figures out, the trouble is some of them (Rogue, Cyclops, Jean Grey, Xavier) can be a little pricey now.
It's been awhile team... Anyone want to update on what's the best available marvel legends stands for all of our new X-Men merch!? Still have mine boxed up until I find good solutions
obitsu stands
I really like these stands, and they are pretty cheap. You can use them for all kinds of action poses including flying.
On a side note, my Uncanny X-Force Wolverine showed up today. It's a big improvement on the previous X-Force Wolverine's and the new claw molds are awesome!
In case you can't live without plastic representations of your favorite Fox produced X-Men films, two companies, Toys Era and Soosootoys have you covered! They produce unlicensed 1/6 scale figures to add to your collections. Here are their newest additions below:
Toys Era
The Cyclopstech
The Creature
The Nightmare
Phoenix Lady!
LMAO, those names are so bizarre The Cyclopstech and my favorite of all the Phoenix lady.
Gross. Best to forget they ever existed.
I hope all these X-Men Hotwheels showing up is a sign of more merch to come. I really want new X-Men LEGO sets.
Not to mention Box Lunch having a bunch of new designs since the last time I was there during Dark Phoenix launch. They even have socks now. Also poke around the clearance rack, I saw those cool Storm shirts at the one near me.
