Skratch Labs is probably the most widely available. If you prefer a tablet, Zenergize Hydrate is sweetened with stevia only, no sugar alcohols - but outside of one race expo where I first found Zenergize, I've only ever seen it for sale online.
Diluting the Hammer Gel won't do you any good, since it's very light on electrolytes even when it's full strength - it's meant to be used as a calorie replacement along with their electrolyte supplement. Hammer's electrolyte supplement is called Endurolytes and it comes in powder and pill form. The powder has a bitter metallic taste since it's completely unflavored and unsweetened, but on those long hot runs I totally need a magnesium/calcium replacement to prevent cramping, and it's not so easy for me to swallow capsules while running (though I've done it in marathons). For cycling I did used to carry the pills, use HEED for on-bike calorie replacement and get sodium from salty foods at rest stops ... but honestly, having to use so many different products is one of the things I really don't like about Hammer's line.
Skratch has two versions: one with a calorie replacement and one with just a tiny bit of cane sugar and dextrose for flavor.
