The PU205 is a nice unit. You have stick, TIG and a plasma inside. You will not be able to do aluminum without the AC mode (Power Pro units). The 200 amp limit is not really an issue for most welding projects. 200 amps is a lot of TIG power. If you do not have plans for aluminum, you should be fine with the PU205. And the plasma cutter is a bonus at that price.
