sorry about the OT drift. Todd (elroymcgee) and i are like a married couple, cant be happy together unless we're bitching at each other.
back on topic, the AR TDS202 is a nice little unit. by itself you may or may not find it to your liking. however, pair it with the Sonic Impact T-Amp (15wpc) and you have yourself a sweet sounding combination. also you will want to get a Y adapter for the input on the T-Amp, and i recommend getting the 12v adapter as well, to avoid messing with batteries. with shipping you can get everything for around $80-$85. ebay is probobly the best source to find the TDS202, get everything else from Parts Express.
to answer the last question, a Kelly Day is a term (from the military) used to designate a persons day off when their shift is normally working. for instance, i have a Monday Kelly Day, when my shift is scheduled to work Monday they do, but i get the day off. where we work, the Kelly Day keeps the work week to an average of 2 shifts per week, which for us, translates to a 40 hr work week.
