It really depends on what you want. With the Ren you have the possibility to use VST's and shit like that, so you don't need anything fancy at all, just keys to trigger. M-audio has a cheap midi-keyboard with 49 keys you could look into. With the 2kxl, I don't know what you want/feel you need. Just a simple midi-keyboard? Or something more advanced-- a keyboard that actually contains sounds? And if you get a keyboard with sounds, you could just use the same one with the Ren (it seems from your first post that you want one each?). Basically, I see no point in getting two (if that's what you meant), but that's just my opinion.
Anyway, 2kxl is a sampler, you could feed it with whatever, and use your pads and the m-audio midi-keyboard to trigger your shit. It's cheaper.
