Hi silver fox ,   I don't have much experience yet but I am looking at a samalex EVO 2224 for my place , it seems to have a lot of nice  features for the money . 
 The set up  and programming doesn't seem overwhelming but we'll see about that I'm not very techy . 
  I've done some work on an outback system  and didn't care for how the programming was done  it was very confusing to me . 
 I from what I understand  the Cotek samalex  and  go power are all about the same .
 But this site sells samalex so I have to Believe that the  Samalex should give good service . 
  I am sure there will be a bunch of guys stopping buy that have way more info to add .

Personally I have both Samlex and Cotek, the Cotek was purchased from Samlex, not  rebranded, both have performed well without the radio interface that the store branded Chinese one produces. The Cotek failed through no fault in design, other than the cooling fan grill being large enough to allow a gecko to enter and get cremated. It was a 2000 watt consisting of 2 1000 watt stacked, I removed the bad half and now functions as a 1000watt, the grill now has stainless steel mosquito netting. Amazingly the overload protection works correctly as a 1Kw, has been in service for 2 years, one as a 2Kw, it is an older mode, which has limitations on input voltage, not high enough to perform equalization without turning off, the newer ones have addressed this minor issue. Are they the best? probably not, but they certainly are not the worst, this goes for Samlex as well, my personal opinion is, don't run too close to the limitations for extended periods, this goes with any electronic devices  and they should probably give a good return on investment.

I have been using Exeltech inverters, they have been great, made in the USA, (that matters to me and I'm a canuck) I have got mine on eBay, apparently Exeltech offers a reasonably priced refurbishing program if your inverter packs it in, they claim a "mean time between failures" of over 20 years. They claim to be used in every US embassy worldwide, and in both the US and Russian side of the ISS, good enough for me.
