DS Daily: Is this an owner or renter's handheld?

Hanheld games are cheaper than console and PC games, which is something we previously addressed, but we're wondering if anything tips the scales, for you, into the region of ownership or into that of Renter's Land, a dangerous desert that is full of vagabonds and cannibals who snatch up lost and lonely games, only to use them, abuse them and later discard them like so much trash. We're wondering if the price, or nature of playing games on a handheld device, coerce you into one camp or the other?

So, let us know how you think about this. Are you one who rents or just loves to trade in their DS games? Or do you have a massive collection accrued somewhere within your domicile (or hidden bunker complex somewhere)? Do you purchase, but wait for the price of games to go down before doing so? Do you use GameFly or rent from the local Blockbuster?
