I invested in M5, and also the Gen3 and Gen4 shapes, to play with in Poser using the DSON Importer.

You need Poser 9/Pro 2012 of course for that.

The downside there is a) it's still pretty slow, for starters, even on a fairly beefy system and b) if, like me you just want the basic character and not the bundle with content you don't necessarily want or need, the thing's not got a penis.

I like Tyler personally too... and he's free, still, I believe, to Poser 9/2012 owners... and /or if you have Blackhearted's GNDA for Alyson 2.

That Ironman13 morph fix pack for M4 looks pretty good too... not got it myself, but I'd definitely take basicwiz's word for it...
