The Genesis1 is like a stripped down J-Station.. It's got most of the same models (substituting the 3 'Johnson' models for 3 'Genetix' ones), and sounds about the same, give or take.. What you sacrifice is the ability to save presets, and it has very little control over the effects..
IMO you're better off with spending the extra $50 for a J-Station..
To the POD killer thing: Each of these units (Genesis1-3, POD, J-Station) has a slightly different sound(not much in the Genesis/J-Station comparison), so it's best to go to a store and check them out. To my ears, the J-Station has better clean tones, and a much better Recto model, than the POD, but that's me.. I also prefer the cabinet modeling on Johnson/Digitech's stuff, more choices, and they just sound more like the cabinets they're supposed to..
The other thing to take into account is the editing software. The J-station's software only runs right on Win98, that's it.. The POD has both PC/Mac support, and the software for each of these units make them much easier to use..
Then there's upgrading, Line 6 wanted something like $50 to take a POD up to 2.0, Johnson offered the 2.0 upgrade for the J-Station as a free download.. I don't use much of their upgrade(J-Station), except the VHT 4-12 cabinet, but I have to give them kuddos for adding 6 models and 7 cabinets for nothing. (though I wish they had added a Soldano model, or a VHT head to go with the cab.

)
In the end, it's all up to your own ears.. Go out and try them all, and see what works for you..
