Thanks for the kind words aesops.tech. To keep this thread as illegible and technical as possible, could I invite you over to here<http://www.saltechips.com/store/> so we can configure yours. Alternatively you can get in touch directly here<http://www.saltechips.com/contact/>, happy to hear from you :-)
