I have dealt with Andrews on a couple of occasions and have had no problems, main item purchased was 12" dob. Service was fine, items were delivered as poromised. Before I bought I rang to ask a question and they got me the answer very quickly so from that side of things no problems. I will also say that the exact same level of service has been provided by very astro shop I have dealt with in Australia, so small markets certainly make for keen service!
On the warranty issue, I didn't even look at or query that with Andrews as I know about the first thing I was going to do with my scope was mod it anyways, so would probably void the warranty with week of it being delivered.
