We would like to get a better quality 2" for overall viewing

A low power wide or semi-wide eyepiece at modest cost is a tough ask. 30mm Superview works okay and it's cheap, especially if you buy used. It's not great in an f/5 Dob but you could do worse. Probably a good idea ask Bintel to swap the 32mm RKE that comes with the scope for one of these.

we feel we need specific FOV and magnification to view Nebula and Galaxies at their most detailed clarity.

That you can have for not a lot of money (e.g., UO orthos), but if you want a wide field of view (FOV) and good eye relief as well, it will cost you, or you need to trade a bit of performance for comfort. The Orion Stratus or Baader Hyperion eyepieces are very good all-rounders at modest cost. Bintel should be able to get the Stratus EPs for you. The 13mm would be the most useful one to get. The 21mm is a nice low-mid power eyepiece as well, although the LVW version (the original which is a 22mm) is a lot better at that focal length. Check out MyAstroshop for LVWs.
One EP I have to recommend is the 8.5mm Pentax XF --- optically this is just about as good as an eyepiece gets, up there with the 10mm XW for half the cost, and with a slightly narrower but still generous 60-degree FOV. O/S it sells for under $US150 which makes it amazing value. I'd be inclined to recommend the 12mm XF too, but I have not tried it. It might have field curvature issues in the 12" Dob.
The 8.5mm I own and it is brilliant. Very useful mid-high power focal length for the 12" Dob.
Grab a good barlow for high powers.
