I am absolutely torn between buying the Tosca or Hill Injection from Dupray. It's driving me nuts. The Tosca gets 72.5 psi while the Hill Injection gets 121 psi. The Tosca runs $996 and the Hill injection at $2299. I am looking for some real positive feedback for any steam owners that get atleast 70 psi. I do only one car a day 5 days a week. The steamer would only be used for interiors and engine bays. My two concerns are: would 72 psi be powerful enough to tackle an engine bay and would it be powerful enough to make a big difference on heavily soiled carpets/leather seats? I could live with shelling out a grand and while $2299 is crazy, I think I could make it work but sure would set me back. I know this topic has been covered before but any extra input would be greatly appreciated. Thanks.
