Another few items to add....
Buying from ebay could lead to savings and let you buy guitars that are not available locally. It typically only makes sense to buy mid/high end models which have more savings because you have to consider your shipping cost and GST.
But there are risk such as:-
1. Item not not as described - there is a blem but seller did not mention coz he felt not important and did not notice but it bugs the hell out of you. You are after all buying based on photos, descriptions only.
2. Item lost or broke in transit. Insurance helps but add to cost and claims take time.
3. You thought you bought your 'ideal' guitar based on photos, good reviews etc having never tried it before since not available locally. It arrives in perfect condition but you don't like it because neck too thick, too thin, too fat, too heavy, color look different etc etc.
4. You bought a fake! This is getting more rampant. You see such things even on soft. So buyer beware and do research. If its too good to be true, it probably is.
