I wasn't around then, but I have bought a ton of older SSC figs and loose pieces cheap after-market.
Bodies: Some would argue the newest SSC bodies have huge issues (the first order of the day with most "improvements" on current SSC figs is to do a body swap, right?) The body which was the worst I have ever had in 1/6 was the SSC Tusken from only two years ago - truly awful; stubby arms, rubbery ratchet knees, loose ankles, etc. However, I have gotten quite a few SSC bodies from the the 2006 era and yeah, not great at all - but not terrible either compared to current SSC bodies (hey, maybe I was lucky with the old ones I got.) I'm a customizer - I have used just about every body from 15 year old Hasbro bodies to 10 year BBI or Dragon bodies to up-to-the-moment HT Truetypes. The idea that the new SSC bodies are a universe better than a 2009 SSC body is - from my experience - not true in many cases.
Weapons/accessories/outfits: I have the SSC Luke Jedi outfit from 2005/06 and it is about 80-90% of what HT would do today. Compare the newest Luke Jedi saber that came with R2 with the one made in 2005/06 - I challenge you to spot the better one. Leia Boussh's outfit from 2007 is incredibly well done (except the pants and to some degree the boots.) The Rebel commando - with the head swapped out for a new DID head and on a new body - comes very close to holding to today's 1/6 standard. I would argue SSC's old gloved hands are better than the current (always oversized) gloved hands. I have a ton of older SSC gear and quite a bit of it (no, definitely not all) is pretty much on-par with today's 1/6 standards - especially weapons and accessories, less so outfits, but not always. People judge those older figs by the head alone and it's just crazy.
Heads: the one area where SSC has improved a lot in the past ten years. But are they on-par with the state of the art 1/6 today? You know the answer to that - you've been following the Luke and Han Hoth threads. NO.
If you think 2006-09 SSC figures are "crap" compared to the current SSC figures, you are not looking close enough. And if you are honestly trying to suggest that the jump in SSC's quality justifies the price going up by a FACTOR OF FIVE then you are crazy. That's not even close to being true.
