Get the 200DX for the extra featuers and welding aluminum.
Also get a Power Ultra 205 combo unit for the ability to have IGBT plasma at low input current, and to be able to also use it on the bread and butter of your work, DC Tig.
If you run into a situation where you need to weld steel that is thicker than you have the heat for, switch the 200DX over and stick weld it.
I would buy both units, and put a small tig torch on the 200DX, like a wp-9. Only use this one for the low amp stuff, and even add in pulse if you need to have less heat.
Use the PU205 primarily setup for cutting.
If you have a bigger project, do your cutting, then swap out the PU205 with a WP26 torch. Grab the 200dx torch for the lite stuff, and pickup the PU205 for the heavier stuff.
Also, measure the actual voltage you have, If you have 240V, it will be a bit better than 220V. I have a 200DX and can confirm full load capability, on AC, with a 30A 240V circuit. I can also confirm that it will do so with a 100+ ft 10awg SOW extension cord.
I'd stick with the pedal that is supplied at first, and go from there if you feel it does not fit the bill. If you set teh current low, and use pulse, the pedal resolution woudl be quite high. I will note that you should read the manual for teh 200dx as well as some of the posts about pedal operation as it is a bit customized to this machine. I am not sure that any other pedals are available for it. If you are not stuck on how YOU think it should operate and instead, actually read the instructions (the file available online, not the included paper manual) and set it up, it works just fine.
You may also want to invest in a nice air drier for the plasma. Seems the cut quality and consumable life is improves with better quality air input.

Any day on a motorcycle like this that ends just needing parts and labor is a good day.
