My Silca Pista lasted 17 years with a few replacement parts, I finally got a Super Pista this year because I wanted more stroke volume. I keep the Pista at my parent's house with an old road bike for when I visit there. The Silcas are expensive ($60) but they are very sturdy, and any good bike shop can sell you any replacement part you could need, although they might have to order them for you.
