Where do you live? I have several relatively cheap +2's (grey).
I also have +2A's and a lot of +3's but they're less compatible with games and the +3 is more expensive.
Also got lots of toastracks, but more expensive than the grey +2 as well.
The model depends on what you want to do with one mostly.
