HSMWorks for Solidworks IS $8-9K, at least it was last time I asked for a quote. Base Solidwords IS $4+K, plus ~$1500/year for maintenance and updates. If you want FEA, that is several $K more. If you want photo-realistic rendering, that is several $K more. There are also tons of third-party add-ons for Solidworks. Fusion 360, with full HSMWorks, for small users, IS free. It does not even offer some of the things that Solidworks does, like FEA, sheet-metal design tools, mold-making tools, but does include photo-realistic rendering.
