Gidday patchk!!
Steer clear of buying stuff off ebay as you can't see it before you get it . What looks good in a picture can be absolute trash in reality .. Uv'd monofilm , corroded alloy etc.. etc...
Go to your local shop or a few shops even if you have to do a bit of driving and peice together the rig of your choice.The newer the sail the better older sails can be easily busted.Being a beginer you want a strong sail because you will fall into it alot.
You should be able to put a rig together for under a grand.Once you have a complete rig you can upgrade indivdual peices and your outlay isn't as much as your first complete rig.Keep an eye on the seabreeze buy and sell ..much better than ebay.
