He will not be getting insurance on anything 150kt fast, complex until he has a few hundred hours under his belt and likely an IR.
Thinking sa fixed gear 182 would likely be best - good ish speed, not difficult to fly, ok access (a collapsable step to aid access and good for checking the fuel too) - ok insurance premiums and much, much less likely to kill himself in it.
Also it depends on where he is going - difference on a 400 mile leg between 135kts and 150kts translates to half an hour or so.
