I second this, I've bought 4 or 5 things from them and always it's been an easy and good experience. I'm in the US so no worry about customs tax, but... they have fast free shipping, I think my a306 came in 4 days and best of all no tax is charged. I don't think anyone here that bought one from there has the bass issue either.
The only negative is no 'satisfaction' returns, only if an item is defective upon receipt. So I don't know what would happen if you got a bass lite model. I consider it defective, but would they. I guess you could ask. I have asked them questions before and they answered quickly. Anyways I'm rambling, hopefully sony fixes the issue soon and then it will be a moot point.
