Manse is 1000 credits... 14 rooms, fountain, oven, shop... plus aetherhold, ramhead, chair, grid, collector, shield, and three turrets. The shop alone is worth 1000 credits. So I personally think that's quite a deal. Am I insane? Maybe... maybe.

Edit: Both of the cartels have been sold!

Somehow, I always end up missing the discount artisan cartels...
