Hello, I'd like some opinions/advice regarding the Athearn genesis line GP9. I normally model in n-scale, but am looking to get a locomotive for use on a family members HO layout. I have found a GP9 that looks good, but I have not kept up with HO - better quality manufacturers/prices to expect etc. The unit I am interested in is an Athearn Genesis. I can get one Tsunami equipped, or I can get one without decoder. Is the genesis line good quality? (I hope so for the price, almost $300 for the Tsunami equipped). Is the non-decoder equipped a headache to install a decoder in, sound/no sound? I haven't had an Athearn in decades - the old blue box was the last one I had. I'd appreciate any feedback/advice. Thanks!
