We started harilo.com 6 months ago and we've been getting a lot of good feedback from Nepalis buying laptops from us to send to KTM.  You can get an idea of prices for laptops at http://harilo.com/deals?hsn=8471.30.00.  We're pretty cheap since there is no customs duty for computers in Nepal and we only charge for shipping.  Indidividual Nepalis buy from us but we also supply to various resellers on New Road and computer bazaar as well as local businesses, embassies, and NGOs who want cheap laptops.
