Owning currently, a Sitemark wraith, a Arken Zulus (now DNT) and both non 4k and 4k Hik micro scopes, my thoughts are,
The Wraith is still good and you can pick one up for a good price but now surpassed.
The Zulus (DNT) makes for a compact unit and has every thing you need at a good price, day and night images are excellent, my only issue is size of buttons when wearing gloves.
The Mk1 Alpex (non 4k) still an excellent scope but loses out in daylight image quality and pixalates when increasing magnification.
The Mk2 Alpex (4k) an excellent scope day and night, providing great day and night image and both models have good size buttons, with the 4k being improved.
If weight is the issue and you want to keep it compact, go for the DNT over the Alpex as many have on smaller calibre RF and air rifles.
On CF full bore calibres, the Alpex seems to be the more popular, being more like your standard rifle scope.
For the money, you can't go wrong with either the DNT or the Alpex.
Reference ANT, those I know who have purchased them seem to leave them in the cupboard in preference for the DNT or Hik products.
My father used to say when buying a car, go with a popular make like Ford, plenty around which means spares are easier to get and your back on the road quicker.
DNT and Hik products seem to relate to that adage.
