Choosing between smc and linksys router+ap, card

I have to decide between Linksys and SMC wireless, router+ap+switch and 1 card, between the pack (1 router,1 card) there is about a 120 us dollars of diference so which brand buy, the most diference is in the router so the linksys cost here in mexico about 100 dollars vs 160 about smc, the cards are expensive but less than the diference in the router,

These are de models

ROUTERS
SMC MODEL SMC2804WBR
SMC MODEL SMC2804WBRP-G

LINKSYS MODEL WRT54G

CARD lINKSYS WMP54G

I'm about 45 meters away from the connection... so what do u suggest to me, these are two that i can buy here in Mèxico...
