Because you like the sales person this is the biggest reason why.

The rest of the 200 features are fully duplicated in the herpstats, eco zone, and herpkeeper lines. For the most part the herpstats offer a low temp shut down, soft heat, and additional flexibility. The eco and herpkeeper are about the same but for the far superior alarms they are capable of. Both units can be configured to email a phone or computer and can be monitored and adjusted remotely. They are a higher price point however the herpstats intro+ is less than the VE with far superior safety features. To get the same in the VE200 you woud need to buy a ve100 to act as a low temp shut down failsafe that is built into the herpstat that doubles the price of the herpstat.
