I went to Hurghada in December 08 and thanks to your posts decided to go with Colona divers. I am writing now to share the experience. All in all, I am happy that I chose them, they were nice and professional.
I went for a full day trip (2 dives) - from around 8 am till 5 pm. The price was 47 euros + 20 for the equipment.
Can't compare prices with other clubs because I had little time in Hurghada, so I didn't look passed Colona. They did give me a small discount for booking the trip online. They accepted payment in euros.
Both dive sights were nice, but I didn't get to enjoy the first one that much because I had problems with my mask. I asked for another one for the second dive and luckily they had one which was perfect.
They gave us detailed explanations of the dive sites.
Lunch was available on the boat for a reasonable price (around 5 euros).
Small complaint on my part is that we had to carry the equipment on and off the boat (and wash it). And they didn't have any spare equipment on the boat, so what you took from the storage was what you were stuck with.
Btw, almost all divers were Scandinavian (it seems that the owner is as well).
Hope this info helps, if you have any other questions, contact me.
