All this info is good for those that are entering the arena of LP playback and looking for alternatives to clean records.
I owned the Nitty Gritty, two VPI's (including the 17F) and now the best one I've ever seen or used, the Odyssey RCM from Germany.
Still, not everyone has been into listening to records for as long as I have, nor do they necessarily know how deep they want to get into it. I agree that the vacuum based machines are probably more effective, but there are people who will be excited about the GEM Dandy and I don't want to be the one to crush their excitement.
Just like the (very long) Lenco thread, it brought a good number of Audiogon members over to the fun and excitement of LP playback and we NEED more young guys in the hobby to keep it alive.
I'm all for entry level solutions, that's exactly where I began when I was a kid.
