I dont actually have my ppl yet, but when i have it and the multi engine rating i am hoping to build a hunderd hours in USA/Canada.
If you have just got your PPL and have just got a ME rating you won't be able to rent a ME aeroplane in the USA. Typically they want 500 Hrs TT 100ME time and possibly 50-100ME time on type.
You could of course rent an instructor for the 100 hrs.......
You can rent a DA40 with G1000 etc., for $99 per hour DRY for hour building (Angel City FLyers) which works out at about $130 wet with lots of airports. That would be your best bet I think.
