I normally won't advertise any company but Seletek`s Armadillo and Platypus are bombproof stuff. And they are in my opinion very fairly priced for the quality and support you get for the money.

Been using Armadillo for years and never had any problems. Here in Finland we have very demanding weather conditions.
Also the support of Seletek is superior.
