Johnny,
Another vote for yer basic dread. Ya just can't go wrong with this bod, and there are a LOT more to choose from.
If your looking for a Guild, you've certainly come to the right place. Look in FS/FT segment of this site - although sales are not that common (we love our Guilds and hate to part with them), fact is it happens. You will certainly get a guitar that has been well cared for. If we were't fanatics about Guild we would not be here.
Other places to look include the ubiquitous clist and eekbay. Needless to say there are both advantages and disadvantages, but if you are an experienced player you can certainly get some GREAT bargains out there in Guilds. There are still generally undervalued in the marketplace, and these days it's buyers market.
This site
http://www2.jaxed.com/cgi-bin/mash.cgi? ... ld&cat=mus is called a "mash" site, and automagically brings together all current listings from ALL craigslists and ebay onto one location. Cewl. It certainly helps you see at a glance what's out there.
The community here also does a great job of trolling the regular places for deals, so looks at the Members Cove under ebays/craigslist/gbase offerings for notable finds. We also tend to post outragious asks and dubious deals here, so it's also a great reference if you see something that might be too good to be true.
Anything D25 and above is going to be a great dread, but if you want rosewood and spruce you will have to search for D 40, 50, 55 or 60. The D-55 is considered by some to be the "flagship" dread that Guild produced, and the extra bling tends to drive prices up. Other Guilds are less known and can be had for good prices.
