Psr-500
I am pretty close to either ordering just a single GRE PSR-500 or possibly both a PSR-500 and a PSR-600 from Advanced Specialties. I like the fact that they include a DC adapter. Is it a Radio Shack DC adapter or is it OEM GRE? (Or do they even make a genuine cigarette lighter adapter?) Also, is there any additional price advantage to buying BOTH a PSR-500 AND a PSR-600 at the same time or is there no additional savings? Are they likely to have these in stock most places? Also, are there any other dealers that include a PD cord? I will likely buy the ARC500 software since it is on sale for one more day.
Are there any other accessories that I ought to be considering? I plan to use the PSR-500 in the vehicle clipped to a Clip Caddy on the dash. I hope that this has enough volume to be heard in the car at driving speeds. I assume that adding an external speaker might not help much because I seem to recall most manufacturers attenuate the audio so that it doesn't damage a persons hearing when listening through an earphone.
The other question is about battery recommendations. I believe the choices are NiCd or NiMH. Knowing that it will be used fairly often in a vehicle with a cigarette light cord, is one battery any better than another for that application or is it simply a matter of personal preference?
