Aluminum Enclosed Trailer Recommendation

I am in the middle of researching a new 7.5 x 16 vnose trailer. I started looking at the steel trailers out of South Georgia and the reviews are less than stellar. So I am leaning toward an Aluminum out of Indiana or midwest. I am going to add 12" to height and some options. Does anyone have any recommendation as to the best price and service to buy? Is any mfg. sell direct? Is it better to go through a dealer?

Thanks in advance.
