Query: BUY THE MIDLAND GXT650VP4 SET!

This is an unfavorable review for two reasons:1) Brunton is significantly over charging for these handsets2) Brunton's customer service's lack of responsiveness.As far as I can tell, Midland has the exact same units selling for as much as $40 less. Brunton has made many innovative products and I assumed this was another and not just some "me too" product with a HUGE mark up.It is possible there is some difference I am not aware of (other than color and branding), so I emailed Brunton's customer service for justification of the big price difference. It's been eight days and I haven't even seen an automated reacknowledgment of my inquiry.
