I like it alot. I don't have an original to compare it to, but it does the job just fine, especially for the amount of $ I paid for it.;)
Thanks for the "heads-up" on this. I tried one of the RhythmTech models and, frankly, found it worthless. I don't seem to be able to bid high enough to get a Ralph Kester on ebay so I have ordered the reproduction you suggested. I'll let you know how I like it.
