Yet nothing shows up in the website for Melcomart EXCEPT a picture of one on one page! Couldn't find any info about it at all. In checking the manf. web, there are now 3 sizes of 'base unit' and each one has up to 6 different size 'windows' for each one. There were only 2 bases and a couple windows for each when we bought ours. I can tell you, if you buy a system NOT from Melco and it causes damage (needle head, for example), Melco will not handle any warranty claims....best to buy it direct from Melco (and hopefully get the right instructions for assembly!) =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
