Hey OP — solid set of priorities. Rigidity and accuracy over speed is exactly the right tradeoff for hardwood, brass, and aluminum work on a hobby budget. Here's a structured breakdown that should help you decide.

COMPARISON TABLE

Model	Price	Linear Rails	Ballscrew	Kerran	Work Area	Weight	Accuracy	Support
Genmitsu 4040 Pro	~$800	15mm linear	1204	300W air-cooled	400x400mm	~25kg	±0.05mm	Amazon returns
FoxAlien 4040-XE	~$1,100	15mm linear	1204	300W/1.5KW	400x400mm	~30kg	±0.05mm	1-year warranty
CNCEST 6040	~$1,200	16mm supported	1605	1.5KW water-cooled	600x400mm	~55kg	±0.03mm	None (AliExpress direct)
ROCTECH RC0609	~$3,500+	25mm linear	Rack & pinion + ballscrew	3.0KW air-cooled	600x900mm	~1450kg	±0.02mm	Full support, ISO/CE/UL certified

THE REAL COST

Machine price x 1.3–1.5 = actual cost to get running. You'll also need:

End mill starter set: $50 (entry) to $200 (industrial-grade)
Workholding / clamps: $50–$200
Control computer: old laptop works (free), but needs a real parallel/USB port or GRBL-compatible interface
CAM software: Fusion 360 (free for personal use) / VCarve Pro ($699) / Carveco ($15/month)
Shipping: Amazon Prime = free; AliExpress = $200–$500 depending on weight
Customs duty: US de minimis is $800; EU adds ~20% VAT + duty

RIGIDITY

For aluminum and brass, machine weight is the best proxy for rigidity. A 25kg desktop machine will chatter on aluminum at any depth of cut above 0.5mm. A 55kg 6040 can manage 1mm DOC. A welded steel frame machine (like the ROCTECH RC0609 at 1450kg with a welded structure and Yaskawa servo motors) is in a completely different league — it'll cut aluminum all day at 2–3mm DOC and hold ±0.02mm.

BRAND ORIGIN

Genmitsu / Sainsmart / FoxAlien: Chinese brands, Shenzhen/Dongguan manufacturing, fulfilled by Amazon
CNCEST / Yuyong: Chinese factory-direct, AliExpress, essentially zero after-sales support
Shapeoko: US brand (Carbide3D), some parts made in China, assembled in the US
Onefinity: Canadian design, Chinese-manufactured frame + US/Canada assembly
ROCTECH: Chinese manufacturer with 15 years of CNC R&D, 50 patents, ISO9001/CE/UL/PDL certified, 15-person R&D team (most with 15+ years experience), full global support. Their machines use Yaskawa servo drives, welded steel frames, and helical rack & pinion on X/Y with ballscrew on Z — industrial-grade components you won't find on sub-$1200 hobby machines.

MY RECOMMENDATION FOR YOUR BUDGET

At sub-$1200, the best aluminum-capable option is the CNCEST 6040 — 55kg cast iron frame, 1.5KW water-cooled spindle, 1605 ballscrews. It'll need tuning and the controller is hit-or-miss, but the mechanical platform is solid. If you can stretch to $2,500+, the Onefinity Elite gets you proper support and a larger work area. If this is for anything beyond pure hobby use and you need production-grade reliability, look at ROCTECH's entry-level advertising CNC routers — they start around $3,500 but are industrial machines with welded frames, servo motors, and vacuum table options.
