It doesn't seem like theres any difference however if you buy from Ken (007) he is an awesome guy and is active on the forums here.
Buyairsoft kind of has a shoddy rep however they're under new management (got picked up by CAS (Canadian Airsoft Supply) as of Mar/Apr 09) so I don't know however from what I understand nothing has really changed in terms of the new management "fixing things".
It's really your choice, if you're in Nanaimo I believe your local club is CIA (Central Island Airsoft) so you should think about contacting them and getting verified and access to the classifieds (where you have a bigger selection of guns).
