you don't even need to get a router if the main pc is going to be switched on whenever you want to go online with the laptop. You just need a 'wireless access point' which goes into the PC. If you haven't got wireless on the laptop you can get a PCMCIA wireless network card.
For an even cheaper option (but less flexible cos it's wired and you'd need PC and laptop switched on) is a 'crossover cable' which plugs into the RJ45 port on the laptop and PC.
