Hi Kingsley, you would be better off purchasing if running for a year or more. Note that if you rent for 3 mths to trial it out, you can apply 50% of the rental pricing towards purchase price. Being a local non-profit, what I could do is get permission to enable you to apply 100% of the rental pricing towards purchase… that way you get to trial it first, then buy it as long as its working well for you and you decide to commit to longer term monitoring ----------- Andy Tolley AmbiLabs Office : 401-247-0100 Cell: 401-369-0844 www.Ambilabs.com www.linkedin.com/company/ambilabs
