I'm pretty set on purchasing the Gaggia Classic in the near future, and have heard the many suggestions to upgrade the steam wand over the standard panarello. Most on the various coffee forums recommend upgrading it to the Silvia steam wand, how does that compare to the latte art steam wand that you guys sell? Also, if I purchased the Silvia steam wand from your parts section, would there be any other parts needed to make that conversion? Thanks!
