I'm lucky I guess.

Just the Ps3. 3 of them. My first one got YLOD(80gb BC model), then my 40gb drive died, and i bought a slim. I fixed the YLOD model and gave the slim to my bro. 40gb model remains useless.

None but my 360 did get the rrod but I've yet to replace it yet

PS1- 3 2 originals 1 slim still own the slim
PS2- 4 2 originals 1 NTSC slim so I could import games that didn't get a PAL release still own it and 1 slim on the way as we speak
N64 -2
Wii -2
360- 2 due to rrod
PS3- 2 due to ylod
DC- 3 still have one in vgc with 5 controllers
PSP - 2
XBOX -2

2x NES (given both)
2x PSX (1 PlayStation, 1 PSone)
2x N64 (sold one, then rebought)
2x Gameboy Advance (sold, rebought, then upgraded, to GB Advance SP)
1x PS2 (got one year after launch, still works perfectly)
2x Nintendo DS (lost one, bought another)
3x PSP (bought launch PSP, then upgraded to PSP 2000 then was stolen, sold PSP 100, now have PSPgo)
3x PS3 (20gb launch, brother broke, then got 80gb, moved to college now have 160gb PS3 slim, which i got 3 days before the pricedrop, then contacted bestbuy, and i got $55 back, yay!!)

i brought 2 DS's and thats about it, the original DS and DSi.

1. My Snes, MS, Genesis and GC are all working absolutely fine. Wii is starting to go I suspect (makes cd rotating noises and occasionally I need to eject a disc and reinsert it.

I never needed to buy a same console... never broke or anything else.

I still have a SNES, Nintendo 64, PlayStation, PlayStation 2 and Playstation 3 working fine.

4 PS2s
The first "fatty" got stolen
The second was a silver slim one, it got messed up from dropping it
The 3rd one was a slim black one, I bought from a pawn shop, and the laser didn't work
The 4th one I sold when I got a PS3

3 GBA's
Hinge broke on my original red one
The other two blue ones work, and I still play them.
