You could also try "Dirt Shop": http://www.dirtshopthailand.com/product ... nm=Product
About Paddock... This is the kind of shop which has always a sale on. You could find what you are after however watch out for quality.Regarding price compared with Europe, I can't really tell but I believe top imported brands won't really be cheaper.
Have a look to this http://board.gt-rider.com/topic.asp?TOP ... erms=Shark already a lot have been written on good addresses and DirtShop is one of those.
Being commuting quite often and just achieving the 65e Esposizione Internationazional del Ciclo e Motociclo de Milano (6~11Novembre 2007) in Italy, I will say that for the small little parts which could be use on small bikes Asia is cheaper but for all others and with the today exchange rate, US is by far much cheaper than Thailand is just spoken about Thailand.
Issue is, if you need the part, it' s sometime more easy to get it on spot than to enter into mail orders and others to get the parts delivered to you down here.
