I would suggest a 2.2 kw water cooled one with ER20 collets. If you do not have 220V power you will likely require a VFD as well.
You will also need to make sure that you will have a mount to hold it.

I'm 90% sure you need a VFD to use these spindles in any setup. I've used a couple on different machines and they all have parameters that must be set in the VFD to avoid damaging the spindle from over speed. I don't have much knowledge of AC power systems but I'm fairly sure that if they were hooked up directly to 3 phase power It wouldn't work or spin far too slow for machining. Likewise I've never seen someone hook one up without a VFD.
