I have our 1998 Classic on a rollout caddy, which makes refilling convenient. I replaced the steam wand with a Silvia V1 and my next project is to install a PID in the near future. Interesting fact, when I first purchased the unit about a year ago from a couple that has used it about 3 times in the 19 years they had owned it, I quickly discovered something was not "right" with our unit, as there was a small current leak that would shock me every time I would touch the body of the machine, and then touch something else (often my forearm would touch the side of my stainless refrigerator). After some head scratching and some careful investigating, I discovered that the polarity of our unit had been reversed from the factory. I switched the pos and neg wires, and there is no longer a problem.
