A KoAloha - although I like other brands also, for $1000 it is my favorite in that price range. I prefer its tone, volume and customer service/warranty.
Well, without narrowing any attributes (e.g., bling or bling-less, fretboard width, radius or not, wood type, body style), etc. it's a wide-open list. Spending close to $1k without going over, here are a few I would consider:
Covered Bridge
Pono Pro Classic
Romero Creations
Entry-level K brand
I'd also consider buying a higher dollar, used uke.
I would probably go right to the Mim, Uke Republic, and HMS sites. Pretty much anything from them would be good in that price range - right now it looks like Imua, Lo Prinzi, and Kanilea are closest to $1,000. I would probably go with the Uke Republic Lo Prinzi at $899 and get a hard case.
But, I would likely kick in another $50 and get the KoAloha Koa tenor from HMS.
