I guess I'm a fan of the more old-fashioned ones...
for the PS2, I would recommend Gradius V (horizontal, though). Raiden 3 is also nice, but not if it costs a lot.
On DC, there's a lot, but none of it is cheap, of course. I liked Border Down best (also horizontal, and it has these Gradius influences). Ikaruga is awesome and stylish but it's not entirely my kind of game. That's not the game's fault though, it's me :)
Slightly older is the very rare (or expensive) ZanacXZanac on PS1, which was Compile's rather awesome swansong.
PSP has the awesome Konami shooter packs, of which most is available on PS1 as well, if you start digging. Sadly I don't have a PSP, but I do have Gradius Gaiden on the PS1 ;)
If you prefer things cheaper, hit the PS2 budget bins. From time to time shmups are to be found there (XIIStag sucked, though :p )
As for emulation, I actually bought Sonic Wings (Aero Fighters) 2 & 3 for NeoGeoCD on ebay and the only way I can run them is through emulation. Technically I'm still being evil with the bios but my own sense of justice thinks it's very reasonable ;)
