Hi jsc
I did end up with Washington Brown and their depreciation schedule does mean that we will be able to reduce our tax liability by more than the cost of the reports which they guarantee anyway. Pricing was really high at around double what you would pay for a domestic schedule at $1,400. Because we were having a few reports done for identical units we managed to negotiate a discount but nothing like what you would expect - still $1,100 for each unit. If you have time to hunt around you may be able to get a better deal.
Good luck
Cheers
Rob
