The Decware offerings are great, but if buying new, there's about a 4-year waitlist. Also, they don't have remotes.
Cary Audio has 2 offerings that will fit the budget, but one is a 300B based amp and only makes 15wpc. That might be fine if you don't listen to loud volumes beyond about 80-85ish dB.
Their SLI100 will have more than enough power, sub outputs, a remote, etc. Plus, with the number and types of tubes it runs, tube rolling is a nice option in the future.

There's also Raven Audio (Nighthawk) and Rogue Audio (Cronus Magnum), Rogers Audio and Quicksilver Audio. All are US made offerings with good customer support.
The Quicksilver is really nice looking with 20wpc, but no remote or dedicated RCA's for the sub out. You would have to run the sub from the speaker terminals.
