Lalitk,
Perhaps you are not at the level of being an Audiophile like me. Once I decide on an item that I may be interested in, I seek out potential dealers. You can do that without my assistance.
The first few questions I always ask is how much, is it in stock, and do you have demo units? Not hard to do, just try it.
They are not gonna be knocking on your door if that’s what you want. You have to be tenacious.
Sheesh, I was a Salesman and a Senior Purchasing Agent for a large corporation each side has its needs. It is not too much to ask these questions.
If they say no, then move on or try another dealer. Many, however, will work with you if you sound sincere.
In the case of Collin he appears to be a nice talker but a small-time operator with limited resources. I have never heard of him before and his website looks anemic. That throw’s up a caution flag to me before I would send him money and hope for a refund.
Have you ever received a refund from him? Has anyone? That would be good information also.
