Hi Mrudo,
It looks like were neighbors - I live in Bethesda, MD.
I bought my TSU-7500 from Dave Darche over at ***
[Link: remotequest.com]. Dave is a really nice guy to talk to and was very helpfull with all my questions/concerns. If you search these forums you will see his name quite a bit.
I also recommend you buy from a company that has a presence here.
Of course I spent about 6 months reading these forums before I thought I was ready to buy.
I have been very happy with my purchase!
