Based on what Ive been reading the LeLit is the way to go. It has great build quality and performance. Most are saying its easily on par with the Silvia and much cheaper. The boiler in the LeLit is directly over the group so it will be saturated, meaning much more stable brew temps without the fluctuation in the Silvia due to the boiler/group being offset.
Dont use Lavazza or any other prepackaged bean as they are stale by the time they reach you. Find a local roaster, buy beans that are 3-5 days old from the actual roast date and you will see what fresh really means. Later!
