The RaceWax.com is a family business, started by a racerkid's dad. Their shipping charges are decent, very fast and customer service exemplary.
Besides offering great prices on tuning equipment, they make their own wax, including a few levels of race varieties.
The entry level race wax, the FluoroMax, offer an all-temperature Fluoro as well as a two temperature combination. Their all temperature hydrocarbon variety is pretty hard - didn't try the Fluoro version yet, but should be the same.
The two-temperature FluoroMax is also offered in a black, molybdenum variation, which is mostly to counter the static electricity on cold, dry snow. I tried their cold molybdenum and works good, not too hard to put on, stays a bit and provides a good glide...
This is great for a simple system, especially since it is meant to be rubbed on rather than dripped onto the ski - so if you are sticking to the simple system, this is a good choice.
They have two, more expensive and more temperature specific levels of Fluoro racing waxes: the Advanced and Hybrid - top of the line. I ordered both of them and will compare them as soon as there's snow,this year.
Both of these more expensive varieties are hard - even the warm ones. There are two very hard waxes at the cold end of the spectrum - hard to the point where the coldest, the T1, is not easy to melt - you can damage the ski if you don't know what you're doing... it has to really impress me with either durability or glide for me to consider using it more often.
What sets thesem apart is that they are meant to rub on thick and then iron into the ski, rather than melt and drip on, thus saving a lot of wax... so, even if the packages are quite small, at 40g and 80g, they will do more skis than a "drip on". However, this rub-on process it is more involved than a regular drip on, which really makes them suitable for racing only.
Choose this system or see more about Choosing Ski Wax. If you choose this system, for training, use their HC warm/cold (found under "All purpose") or even some others, like Kuu or Hertel.
I wouldn't use their fluorinated variety for training because the rub-on process is more involved than just melting and dripping some big cheap block of wax. If you know next day will be wet, sure, go fluoro.
For racing, part of a simple system, you can use the FluoroMax two temperature blocks. It is good enough not to look further, for beginning racers.
For a more advanced system, move up to the more expensive options, for the probability of extra-speed, if your racer could use it!
