hire cars frankfurt airport

Hi anyone know of a really cheap car hire company from Frankfurt Hahn airport?
I ‘ve found a one co, Sixti which does a car for 2 days for £60.
Sixt charge €99 while Sixti charge €60. Are there are better?
Thanks to all who offered suggestions so far. However I should have emphasised the word KNOW in my question as most of the suggestions are for firms which charge quite alot. So once again if anyone KNOWS of a cheaper firm, then i’d be pleased to hear, thanks.
Besides Sixt there is no other rental car close to Hahn Airport since it is a very small airport belonging to the “mother-airport” Frankfurt. Hahn used to be a military base for airforce, but it was closed down and that’s when civil airport Frankfurt “took over”. In case you need to get to Frankfurt from Hahn, best bet would be to catch one of the transfer-busses. They go all the time and might even be free of charge. There is no trainstation nearby, either. So, like I said, in case of needing this rental car just to get to a bigger city, best bet would be taking the transfer-bus.
