Since several PIClisters have purchased Cybiko Classics and may need replacement batteries, I thought I'd mention that Jameco also has the F6 Prismatic NiMH batteries also and at a very good price. http://www.jameco.com/cgi-bin/ncommerce3/ProductDisplay?prmenbr=91&prrfnbr=431761&cgrfnbr=773&ctgys=503;527;773; The other online source I know of is: http://www.multimeterwarehouse.com/F6f.htm I purchased 4 batteries from multimeterwarehouse.com and their service was great. I ordered them Monday morning and they arrived today (CA to KS in two days via USPS Priority mail).
