Thomann; however, it has not gone smoothly. I asked them to expedite shipping due to their pretty poor customer service (I sent several emails and left voice mails without reply). In fact, in order to call the UK, I had to set up international calling on my iPhone. I'll let you know how long shipping takes. I also asked about whether there will be US customs duties - probably not since this is for personal use.
My only concern getting one from Europe is if the unit fails, then where do I go for repairs? Also in case i don't like it, returning to Europe will be a bitch to deal with, specially if there is only a short amount of time allowed for returns, + there might be customs fees(depending on the mood of the customs person working that day.. )besides the shipping costs. I travel to Europe frequently, and I can easily pick one up there, but just don't want to deal with any of these issues, so I think buying local is the best option. With all these delays I might actually get to try one in Europe, a friend of mine bought one, but I think he needs to return it due to some problems with the unit, but he liked it so he'll have it fixed or a replacement, so maybe i'll make a decision if I really want one by trying his KPA, if we have enough time to get together and try it.
