I have a Diamond and love it, However, I bought it when it fisrt csame out and paid 9K+ for it. My friend bought one at a LQS truck sale and paid 5K about a year ago. They have some problems so I would want to know when it was purchased and what LQS will service it. I had to have mine completely replaced after 9 months of BUGS and so did my friend. With that said I LOVE my Diamond! That is a very low price. If it is a good one, what a deal, if it is a lemon, well you will have months of problems. Good Luck
