I am aware that member Jim Good sells these, however. he is difficult to contact. I have sent him a PM and called a phone number I believe to be his. I purchased some nice ones back in the summer from Northwest Acrylics in Salem Oregon. I contacted them today and they told me they no longer carried them. I have a new customer that I need to service with some 12" bases with 1/4" acrylic quickly. Does anyone know where I can acquire some similar to the NW Acrylic type on fast basis? I definitely need the ones with the power supply, set up and ready to slide the acrylic into and plug in. Thanks in advance for any info on a supplier.
