Hey Pluto,
First off a little more info. you be helpful so that we can better answer your question. Example what type of diving do you do? What type of diving will you be doing in the future? Do you want to get into tech. diving? How many times a year do you dive?
That said here is my opinion. If you are looking at the Hub don't look at Dacor look at Mares. I know that they are owned by Mares but the Regs. that the Mares Hub and the Mares Hub Avantgarde use are alot better than the Viper Regs used on the Dacor.
Here are some +'s of the Hub system.
Nice for Travel.
No chance of forgeting your regs.
The power inflater / deflater
Here are some -'s of the Hub.
Price @ your LDS.
Extreamly bulky - I tryed one on at a dive shop and it is huge. All hoses are ran to a copper y behind each pocket for the Reg. and Octo on the right and for the inflater/deflater & gauges on the left. This makes the pockets huge.
No chance of moving into more tecnical diving with this setup.
Will not carry doubles.
Hard to service.
If your Reg. has a problem you have to leave to hole system to get the Reg. fixed.
When I talked to the dive shop owner where I tryed one on, he said the only people he would recommend the Hub to would be someone who only dives 5-10 times a year and tarvels.
If you are really interested in the Hub I would recommend you check out the following sites. Their prices are about half w/shipping.

If I was going to chose between these I would go with the Mares Hub Avantgarde.
