For my own needs, I wouldn't be buying the machine you mentioned. But.....
When you've considered all options, look at why you initially wanted to buy another Prochem machine.
Do the alternatives have comparable performance?
Do the alternatives have comparable reliability?
Do the alternatives have comparable technical support?
Do the alternatives have comparable local dealer support?
Do the alternatives have comparable levels of quality service?
Prochem have set the bar very high and so will be a tough act to follow. Just look at the experiences of some CIU members who bought a Speedster

Only when a product ticks all the boxes can you purchase with confidence.
BTW Many Prochem dealers often offer better deals than Prochem themselves, so shop around. Also, if it's of value to you, you often get a free prochem training course when you purchase one of their machines. Even if you have attended these or similar courses before, a refresher is always useful.
Safe and happy cleaning

PS
Try suppliers such as Restormate, Cleansmart, Cleaners Warehouse etc. etc.
