I have a couple. Lovely fabric, really nice collars and gorgeous buttons. All round I'd highly recommend them.
Other options are Borrelli (although from recent reports they may be decreasing their quality), Finamore of which I have one - nice shirt but I prefer the Kiton, Barba, Lorenzini and Pal Zileri Sartoriale.
All at full price are likely to be cheaper than Kiton but of course if going for discounts this can vary greatly depending upon what you can find.
