plenty of other options, just ebay can give you world wide exposure and with the A$ at .75 to USD you would like to see a lot of americans having a tip at it. make sure you load the postage tho as it wouldnt be cheap.
otherwise there are plenty of others such as facebook old yammie groups etc to keep it local in aus.
as for getting a price its a difficult one. if you search all over with ebay and gumtree etc see what these are selling for and make a value judgement.
thats why teh ebay auction style sale solves that issue...if enough punters see it and want it (you can facebook Oz Vmx etc advertise too all and sundry) , you will get the best price on the day...that may not be what you think its worth and thats where a reserve comes in with all its hassles and haggling.
Punters who are into DT stuff will want it cheap so an auction sorts that out as well. there my thoughts. there will be plenty of others and you can decide whats the best way to go....
