He probably has at least 50. I switched to Virtual Weather Station with my Oregon Scientific unit, but would be willing to switch back to WD, or even Cumulus, if I decide to get one of these stations. I'm a NWS meteorologist and I will be quite interested to see the reviews, with regards to data quality, before making the jump. The potential for these units is exciting, and with the low price, I suspect it will get alot more people into the hobby. Hopefully the data quality will be sufficient, and there will be ways to upload to CWOP, PWS, etc, if one of the major software programs supports it.
