Just curious if you went ahead and purchased the HP2553?
Of interest the Canadian price dropped on Sunday - February 9th with a $20.00 Coupon off on the Amazon.ca site. At $399.99 I don't think they are moving since the price is $80.00 more that the US Ecowitt site.
I have contacted Ecowitt about this price discrepancy since the Canadian Amazon and Ecowitt US prices are very similar. I would like to see the price drop to $349.99 with the $20.00 coupon bringing it down to $329.99.
I am looking to get one but the weather is on my side - still buried in snow so I couldn't even mount one until late March or early April.
