I have the LaCrosse 2317-EL and have been very pleased with it...runs quietly and is a workhorse...the software I use is from the WUHU guys...have been very happy with it.
I upload information to HamWeather (Weather For You), CWOP, Wunderground, and AWEKAS...again, it runs like a charm and the WUHU Yahoo Groups site is very helpful...think my bride and daugther paid around a $100 for the 2317 on Father's Day of 2006....just helped a resident of our county purchase one of these and get it running...he is pleased also.
