I have several midrange PR/5frw SCs and the fire/lite ones I posted earlier...what were you thinking for value vs the skiller?
As for spiderweb sashes, they can't be shopped (any patch) or gambled (pre-1.10), but can drop from most any mob in hell in 1.08 (can't drop from mobs in 1.07)...atma sez best chances are in act 3, but meph and andy can drop them as well, if you were running them...
No idea. I don't value mid ranged resists much but I won't ever use the skiller, so whatever you think is fair would be OK for me. The skiller will be in better hands ^^
I'm in a middle of a format so I can't recheck my 1.08 stashes, but I think I don't have any blue spiderweb sashes there. When I ran Andy I only picked charms/amulets and some uniques/jewels to try and making them as faster as possible. Maybe I'll try some runs and hope to get some for you (no promises since I'm pretty much bored of D2 since the MFO).
Out of curiosity, what (-if-) could make you eventually think in trading the f-o-r-t-y-p-r-e-t-t-y-t-h-i-n-g?
