Super Serious Question

ok, so i just got a lot of money cause my dead grandpa's will just came through. and my parents ( im 15) said if i wanted to i could use a little bit of it to get a PS3. so i called my local EB Games, and for a 40gb PS3 its only 399.99 and comes with call of duty 4, and the 80 gb is 499.99 and comes with some extra crap and motorstorm. And i read up that for around another 100 bucks that i could get a 2.5 sata thing that would give my ps3 like an extra 160 gb. but i was watching reviews on the run and they said that o play lost planet on the ps3 that enven though its only 5 gb they had to erase stuff on there hard drive. so i was wondering if 40 gb is going o be enough for me cause i only have like 15 games for my ps2 and if 40gb isn't enough for the standard gamer but 160 is to much then i can get a 80, i just want to know what is the best and about the hole havibng to delete stuff to play new games. thanks

buy the cheapest one and upgrade the HDD for the extra 100 you pay buying the 80 you could buy 160gb plus cod4 is a great game to get with the system.

Wait and get the MGS4 bundle. You probably won't need anything bigger than the 80 gig drive that it comes with, at least not for a while. You can always upgrade later.
