As in swapping out the asa for an on/off one (from an axe?) - or adding an on/off that goes between the existing asa and the tank - which is cheaper - but does it mess with the balance/feel/etc?I would invest on a mini but buy a few upgrades like a flip asa for it, youll still have more money left over than you realise but jusy still use an aluminium tank for now and keep the rest of the money to keep on playing
