The best bang for you buck will be an MRC IMO.

I ran an MR2 on my 90 and now extended that to an MR3 (single beckett) for my 120. I would think about an MR3 with 2 becketts or an MR4 for your size tank.
IMO you will have to spend around $1500 or more to get a good needlewheel for that sized tank. Like has been mentioned Deltec, H and S and Euroreef are all good skimmers. Geo would be my personal choice for a needlewheel. I have never used one but some people to like ASM's and others think they are junk. The ones I have seen have not impressed me but maybe I've just seen the wrong models

I do know you want to avoid the Sedra 5000 pump.
Some advantages to becketts are:
You can run an autotopoff container (a huge advantage for external run skimmers if you don't like water all over your floor from the occasional overflows, also works with ETSS)
More skimming power for your $
If you skim wet you won't have to clean the cup but every week or so.
Disadvantages:
A bit harder to learn to use
Use more power.....it should be noted that the larger multipump needlewheels when you add in the recirc pump use about the same though.
Here is a good recent debate on skimmer type pros and cons:

It should also be noted that it's a good general rule of thumb to get a skimmer rated for about twice the tank size you have.
