We have two older one's (6 years plus) in our drive through. They are two head machines and are not the tall one's. This means I have to steam my milk and shoot my shots into tins rather then directly into cups.
We just purchased a 2 head for the mobile unit - its awesome. I love it. We can shoot shots directly into a 24 ounce DART cup and steam in the same cup - no tins.
Great machines....I think they will last forever. I have had one go down...but I'm glad to have two.
La Spaziale is great. The roaster I work for has sold about 150 La Spaziale machines over the past two years. They make a great extraction and they are well priced.
As for them being well priced, keep your eye out for indie cafe alliance. They will be working with La Spaziale to provide a 23% discount on La Spaziale machine to members. Check out www.indiecafealliance.com !
