Somewhat OT: Airport questions

[Riba]

Hello people...I need some feeback on this.

Few days ago I got the DSL connecion at home, and considering that I 
already have airport card in Cube and a brand new Powerbook on the way 
next week, I thought it might be nice to put the wireless router 
somewhere and forget about the cables.
I'm not a wireless freak though, and I'm even cosidering getting a 
802.11b wireless router because I believe this is more than enough for 
the planned use. Of course for just a  bit more $ I can get a 802.11g 
router, but considering that my cube has the old airport the speed 
would be bumped down even with 802.11g router when using the Cube.
What I'm actually considering is to get an older graphite base station 
(I noticed one can get them for a decent price on ebay). I recall about 
some older base stations exhibiting some problems and recalls so I'm a 
bit wary at the moment. Anyone on the list selling a graphite base 
station? :)

Am I stupid for considering buying and older technology? Would I regret 
it down the road? Any other suggestions?
