Opinions - Ether vs. Nitrous

[RoboCop]

Alright I have tried Nitrous on several occasions but all just from a whipped cream cans ( still fun as hell ). And this shit can be very expensive if you plan on getting high off of it alot, expecially because how short the duration of the high is. So then I started researching ether which seems to be easier to get, because you can make it from starting fluid and get alot more out of itbecause you canjust pour some on a rag whenever you want to and enjoy. ( sounds good ) I am not into inhalants (and will never use any besides these two)but these two seem to be very fun. Anyways my question is which would be best,cheapest,safest,and easiest to obtain? Is it possible to purchase a tank of nitrous? (I wouldnt think so but god I hope so) Does this method of making ether from starting fluid work well? Is it worse on your health? I know nitrous is actually not very bad on your health it is a minor dissociative but it is the safest out of all of the dissociatives, and me being a person who has done DXM hundreds of times with no bad effects this kinda makes me think of nitrous as a nice and safe inhalant. (oh and I have not been able to get a hold of any nitrous cartridges anywhere)
