Ok the first 2 seem to be trash, why they were regged is anyones guess. Maybe firstgood is brandable im not sure.
Limitedsale.net.. tricky one. I think it has potential. Either as a sales site or for a company which sells limited companies. I dont think its a bad domain. Though maybe not great. Maybe $30 reseller value though that is pushing it a bit. Maybe alot more end user value.
