Welcome.
I know this sounds like a smart a$$, unhelpful answer, but I suggest you visit Guild's
web site to narrow your search.
If you want new, with a street price at $1000 then assuming a 40% discount from MSRP (which is not always a reasonable assumption with Guild, the way it apparently is with Martin) then you are looking at a MSRP around $1600.
Guild is pretty much fragmented by factory. I don't think anything coming from the New Hartford factory has a MSRP that low so you can rule out the Traditional, Standard and Orpheum and perhaps a couple of others. The Korean factory is only making electrics, so that is out. The Mexico factory makes the Arcos line and some of them fit your budget. The Chinese factory makes the GAD line and those are also within your budget.
My local dealer loves the Arcos line and can't keep them in stock. He is going to drop the GAD line because they are not competing well with the non-Guild alternatives in their price range.
LTG seems to have little experience with the Arcos line. LTG has a lot of experience with GAD. There are a lot of folks who like them, period. There are a lot of folks who hate them although most of the "haters" seem to have a general hatred of "cheap" guitars and the compromises required to make them cheap or "hate" for reasons that have more to do with international politics and economics than the guitars themselves. There have been some well reasoned criticisms of specific models and several reports where there was inconsistency within the model line.
Your best bet would be to narrow your criteria and ask about specific models.
I also have to suggest that $1000 invested in a vintage Guild will almost certainly get you something as good or better than any new Guilds available today that are not made in New Hartford.
