I really need these equipment but not so many for this first time, and your price quoted is not cheap.
I also hope you could understand these are all the second-hand equipments, so I will pay the subscription after the goods inspection. After all, it is fair for this is our first deal, and that will guarantee us out of some unnecessary troubles.
Once this deal is settled, I look forward to have the opportunities to make further cooperation between us.

I really need these facilities.But not so many for the first time.And also your quoted price is too high.
After all those are second-hand facilities,I hope I could pay the earnest money after I checked those facilities. I also hope it will be fair to both of us since it is the first time we deal. It also could aviod the unnecessary problem in future.
I am looking forward the next cooperation, if we could make the deal.

We do need some equipment of this kind, but not much for the time being. And, to be honest, the price you offer is a bit too high for us.

We'd like to pay the down payment immediately after the sucessful open-case inspection to avoid all possible troubles. This would be fair for both of us, since, after all, this is first time of our cooperation and the devices are all second-handed.

We hope the above are acceptable to you and would like to establish a long-term business relationship between us.
