The very best thing you could do Is stick with the dealers here at RWG,are dealers sell the very best reps available.Hublots with the a7750 can go from $250-$600.00,depending on what you want, I would say you can get a very nice Hublot for around $350, there are some decent ones that are less than that. Read some dealer reviews than read some Hublot reviews. In no time at all you will be ready to purchase your new rep with confedence. All the Infomation you need Is here,so read up and enjoy this awesome community. Of course ask questions when you have them.
