Well, since nobody seems to be willing to share pictures of the Sandtrooper anywhere on the Internet, I tought I'd buy one to see it for myself. It's my first Mafex and I was a bit worried with all the negative comments but I must say I'm not disappointed. It's a really nice figure and even if it did come unglued in the midsection, I have no complaint whatsoever with the QC or "flimsy-ness" of the figure. It feels like high quality plastic, solid and with joints both smooth and firm.
It can hold standing straight poses of course but also deep action poses. The backpack does come in the way, though. It's hard to have the midsection the way you want.
It fits in well with my 6" Hasbro figures. Up close it does look higher-end but from afar they seem to belong together. Only the FO Stormtrooper looks a bit toyish in comparison due to the shiny white soft plastic.
There, you can see there is not much difference in the paint app between Jango and the Sand, but I do think Jango is one of the better BS figures.
In the end, even if I am really happy with my BS figures (Deathtrooper and Jango are awesome), I feel like it's worth spending more and go the Medicom way, for some of the figures anyway. For others, not so much. I'll probably end up with a mixed collection of both.
Cool, fun and affordable figures either way. Love 'em!
Edit: I do wish this Sandtrooper came with more accesories, though, like white and black pauldrons, binoculars and the big-barrel gun.
