Gamma Scopaline/DMSO, Costs how much? Options

[fistandantilus4....]

OK, good ol' GS is listed in SR3, pretty effective little tool . Sure everyone has done the DMSO combo.

But looking in SR3, there's no price that I can find. My Cannon Companion has recently, well, gone the way off half of my socks. So can't look there. Anyone got a cost (w/ Street index) for that and DMSO? My players are wanting to do some heavy hosing of some gaurds, and I'm hoping quite honestly that it's cost preventive.

Also, one of the characters has a biotech 8, and chemistry 8 (knowledge skill). Any thoughts on time/cost/target number to make the stuff? I really have no clue what would go in to making it. If it's just an extract of Belladona, makes sense that she could do it with a shop, but other than that... no clue.

Personally I would much rather she NOT start making something like that in large quantities, because it could be very unbalancing. But I'd prefer to have runners hit her shop and swipe it after having it for a while than just say "no". I try to never say "no", just assign a target number (or consequences). Unless someone wants to dikote their tail of course. ;) So I need some rules on what it would take for her to do it.
