I'm not sure why this is supposed to take hours, just stick '2.2kw spindle' in the search box and sort by price and a few minutes later you'll find this:
UPDATE 2.2KW WATER COOLED/ER20/JAPANESE BEARING SPINDLE MOTOR AND 2.2KW MATCHING INVERTER-in Other Machinery from Industry & Business on Aliexpress.com

£229.70 at time of writing, with shipping via Fedex or DHL so within 3-7 days. The spindle I ordered from ali-express most recently came without customs charges, although that was one with lower run-out and ceramic bearings so more expensive.
