You can buy a PSP 3000 with a 16gb memory stick for less then $250.

My answer would actually be the PSP 1000, because it does all the same things and is much cheaper. 

3000.  Same hardware, much cheaper, cheaper games.
I only recently bought a 3000, and I'm very glad I did.

PSP 3000, bigger screen, does everything the PSPgo does, plus it had umd drive, and it's cheaper.  However, if the 3000 was more expensive, I would buy the PSPgo for sure.

psp 3000 is cheaper, has cheaper games, and is pretty much better then the PSPgo.

Well if you like physical discs and can find yourself a memory stick bigger than 16 gigs then the best way is PSP-3000.

The 3000.The Psp go just seems like a waste of time on Sony's part.

3000 - by the time (and if it even does) the Go is in full stride and gets a price cut, there will be the PSP2 in the works, if there isn't already now. Mark my words.

3000 - physical media ftw.

I would get a Go, mostly because I sold my PSP-1000 and don't own anything anymore.

I like the look for the Go, but I can't get past the games issue.  If Sony figures out a way for people to transfer games they bought on UMD to the Go, I am open to purchasing one...once they drop the price by at least $50.

PSP Go!. 
I've either beaten all of my old UMD games or don't really have much of a desire to play them. I really like the PSP Go!'s aesthetic and ultra-portability, and most of my PSP games I already have a downloaded version of. Also: my PSP's Memory Stick Duo is actually a memory stick micro with a duo converter, so transferring everything over would be easy, too. 
 
I don't get all the Go! hate, especially about it not having a UMD drive. Does anyone still regularly play a PSP game on a UMD? Does anyone like the UMD format?

I'd rather buy a PSP 3000. A PSP Go is just too expensive for me, and I don't see any reason to graduate straight to a PSP Go.

i would go with PSP go. it's newer thing out there. i'm not sure what it has and things as i don't play handheld. i'm more of a console gamer.

I used to be an avid Video Game Collector and as such, need all the space I can get and I don't have much, so I pick the Go.

im just going to wait until the go drops in price (which it will) then ill think about getting one. and even then ill wait until peacewalker comes out for it

The 3000 is more appealing right now but rather than buying one of those only to then set it aside when the Go is cheaper I'm just going to wait for the go to get cheaper and then buy it.
I'm willing to bet the 3000 will be slowly phased out and new psp games will eventually only release on PsN, by then hopefully it will have that price drop.

I recently bought a PSP 3000 and was torn between that, or waiting for a PSP Go for a short while. But really the 3000 has all of Go's features + UMD and it's cheaper. I also prefer physical media.

I only have 2 PSP games, and a 2000, so I might grab a Go.

PSP 3000 all the way!!!

Ben Kuchera at Ars Technica just obliterated the PSPGo!  It is a pretty awesome review.

PSP Go... when it drops down in price.
 
I don't need physical media for my handhelds.

psp 3000 mainly because of the price. i like the look and concept of the psp go, but I'm low on money and you can get a psp 3000, final fantasy Dissidia, and advent childern for ownly $200, saving me $50 to get even more games.

" I think that "review" was pretty poor.  It came off as just fluff and says I hate the 'GO' blah blah blah.  It seemed that he didn't come at the device with its merits and faults.  Ars Technica are usually really good at their reviews but if he hated it so much that he should have just wrote 'Go sucks' on one page and be done with it. "

I would get a 3000, the Go sounds cool until you realize there is no way to turn UMD games into Go games. They should really do some sort of PSN connectivity with the original PSP and the PS3 or somehow make it so you can authorize your PSN account to DL UMD games you already own onto the Go.
