Sigma Raijin, Sigma AV7000, Pana ..., which is the best?

[Red Hots]

Compare the following superguns:

1) Pana Custom Long
2) Pana Twin MP-92
3) Sigma AV3000
4) Sigma AV5000
5) Sigma AV7000
6) Sigma Ranjin
7) Vega 9000DX
Vega Jr.
9) Wintechno Play2

Which one is the best for shmups? Which one is the most expensive? Which one is the cheapest? Which is the most economical? I'm looking for a good supergun at a reasonable price, which doesn't occupy too much space.

AV7000 is very small (but heavy). The 9000TB (the stick that goes with it) is pretty big I guess. The Raijin takes up tons of space, but you can play two player for an affordable price. I don't know anything of the other items. You'll be hard pressed to find AV5000/AV3000 peripherals these days, so you best forget them (unless you're solder savvy).
