This was $49 until some day ago directly on Softube, $39 for owner of tape. Can't compare this with Fx collection, totally different things so it depends from your workflow but if you need some good effect to add in your arsenal, Fx collection is the go to.
Forbidden Planet is $142.04 at JRRshop while at Audiodeluxe for the same price get ElectrumCore for free and $7.18 DeluxeBucks.
Looking to buy Forbidden Planet from a while now, but still undecided....
