Original poster: "Peter Lawrence by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Peter.Lawrence-at-Sun-dot-com> Radio Shack is having a sale on 20MHz 2-channel scope with built in 1MHz function generator for $400 (Instek model GOS-620FG). Anyone have any comments on this brand/model, and is the built in signal gen worth the extra $150. thanks, Pete Lawrence.
