Hey Bret, welcome to the ANZLF.
Resaw is when you get a thick billet of wood and then slice it into thinner bits for guitar back and side sets. This is a good way to get cheaper wood but it comes at a cost because it requires largish bandsaw that is set up for the job 'and' you need to understand what you are doing 'and' you need to understand that a billet of wood does not always produce good guitar sets. Sometimes you cut them open and find a big sap vein and that sort of thing eats into any savings you make.
If you are just starting out in guitar building, then my advice is to forget the big saw and just buy a few pre cut guitar sets from a reputable tonewood vendor like Tim Spittle of Australian Tonewoods. Later with a few guitars built, 'then' there may be benifit in setting up to re saw and then you will know more about what is best for you. For now, I would get the 14" bandsaw (10" are just too small) 'and' I would be on the look out for a secondhand one to come up in the local paper. The formula is simple, see what the secondhand saw sold for new and if it is in 'as new' condition, buy it for no more than 2/3 replacement cost..anything with a few knocks and bumps, pay no more than 1/2 new replacement.
As for brands, JET tool are quite good but you will pay more. Service may be crap in SA (seem OK in WA) no idea in QLD, but I will say that a better quality machine will require less use of service anyhow. Carbatec, I have a 6 x 9 sander and it is OK...not great, not crap, just OK, I would rank all there stuff on par with, or maybe a little better than the orange coloured Sherwood stuff that Timbecon sells. But the truth is probably that the only real difference is the colour. Hafco..I don't know cause I don't have any. But from what I understand they sit somewhere below JET and a little above Carbatec/Sherwood.
Anyhow, if I was you, I would just get enough static power tools to get by for now and worry more about getting some good hand tools and lutherie specific stuff like an Ibex fret rule, a set of nut slotting files, crowning files, tang nippers, bridge pin hole reamer and stuff like that. If you get a full blown habit, 'then' start looking at the big shinnies, but right now the AUD is good against the green back so Stwart McDonald and LMI is a good place to spend your money.
Cheers
Kim
