Stay away from them
That's probably wise
I used to only bother with 3 3/4" but when Sideshow came around my friend got me in to them. I've actually been pretty restrained on getting them, only have 6 total over a good number of years, so I'm not too worried about going broke on Hot Toys.
If Sideshow would make a Kylo Ren or Captain Phasma then I'd probably wait for those versions, but I just don't know what's going on with Sideshow and The Force Awakens.. seems like Hot Toys might be the only option there.
