Never go back to the capsule machines. They all still suck.
An Aiden would be a good choice to supplement the Profitec but you could also look at a Clever Dripper which will do up to 500ml of brew at one time. Do you have a seperate grinder that could be used with a Clever Dripper?
I use a Clever Dripper at the office because it uses very the least amount of my time to make a consistently good cup of filter coffee. It is also quite forgiving if you get interrupted and the grounds steep for a few minutes longer than planned.
