My fiancee and I went to Litemode and picked up some really nice lights for excellent prices during their Boxing Week sale (2007).
We picked up a floor model (last one) for 1/3 of the original price and their electrician, Mario, did an amazing job with adding on custom glass leaves for no extra cost. Their regular prices are on the upper end, but they do have quite a big selection and they carry very nice lights.
The staff is friendly and helpful, but a little slow when it comes to actually making the purchase. All in all, it's been a great experience. I'd definitely check their store out again!
