[Test-Equipment] giga 6061A vs HP 8656x

[Eugene Hertz]

Hello all, 

looking for an rf gen to near about 1Ghz or so.  Been thinking about the HP 8656B or possibly 8657A depending on what I can get for cheap(ish).  Came across a gigatronics 6061A for a few hundred less that the typical HP units and was wondering, is this a decent unit? Should I stick to HP? Should I avoid the 6061A like the plague for any reason (reliability, parts, etc?)

thanks
Eugene
