Daylate, the disadvantage ( being on the AIM ) is you might pay a healthy fee every time you buy or sell, somewhere in the hundred dollar range( according to the E* customer service rep
I spoke with ). You also might not be able to transfer over retirement accounts.
An advantage would be if the AIM stocks have options ( calls, puts, leaps, ETF, etc ).
I would like some more discussion on the subject too.
