amp suggestion, jl, soundstream or kicker?

got decent quotes on the following amps.  People more knowledgeable than myself say there`s more to amps than the power.  So I`m asking if anyone has insight that could help me pick one.   They will be powering two Type R 10s, needing 200-500 watts each. 

I have no experience with any of these, and given my setup, should I care that they seem to be the manufacturer`s lower end goods? 

JL JX 1000/1

1000W x 1 @ 2 ohm (14.4V)1000W x 1 @ 2 ohm (14.4V)

Soundstream L1.1100D

800W x1 @ 2 ohm ((14.4V)

Kicker DX 1000.1

1000W x 1 @ 2ohm (14.4V)

Other than these, I was leaning towards an Alpine MRP M1000.  I also got a quote for a JL XD 600.1 for $450, but I didn't think it was enough power; although the sales guy said it would "pound the crap out of those subs". 

Any thoughts?

im sure you got your amp bought already, but i thought i would add an opinion the alpine gets extremely hot @ 2 ohms, it rolls back the power quite often (thermal protection) on a 1 hour commute to work daily. this down south heat is big factor, canuck country mite not be that bad other than that, it puts out big power @ 2 ohms the other three amps are from reputable manufactures, i would think you cant go wrong1000 watts of lp, now need sum hp an mids

Kicker makes great amps in the ZX line but the DX is not in the same ball park as the JL. Between thoes amps Id go with the JL of get a Kicker ZX1000.1

Definitely JL, the other brands don't compare.
