MIG Aluminium Welder

I’m looking to do some alu welding… have experience with iron (oxy, mig and stick) and alu… but only oxy…

So I thought I would get a new MIG machine, something not too expensive as it’s just for the occasional thing.

Found these two on amazon at a reasonable price:

Does anyone have any experience with either? Or another machine in the sub-500chf range?
