I would say if you're willing to spend $380 spend less than $100 more and get one that isnt polymer. PSA, Radical Firearms, etc all offer a good product under $500
I have no experience with the polymer myself but i know in the past there was problems with the lower breaking at the buffer tube.
This is the age of the $300 AR. If you don't mind pushing two pins in, PSA could provide a complete lower with an aluminum receiver and a complete upper for less than the price you quoted for a polymer gun.
I can't argue with Larry's view for the long run. But, I do have one omni, and I like it. Ymmv.
