Sub Gear is essentially a lower cost option to Scubapro and Uwatec. Exactly the same stuff just with a different cosmetic treatment. Sub Gear is a different brand name owned by Scubapro, and Sub Gear items can be obtained sold by any Scubapro dealer.
The difference lies in lower price and reduced warranty coverage. For example the sub gear version of a Mk 2 R295 can be bought for less money but it comes without the free parts for life warranty.
The wholesale dealer cost however is basically the same so whether a dealer sells it or not depends on how they look at it. It has a lower profit margin, but it tend to be lower end /entry level items anyway (like the Aladin Prime, Mk 2 R295, etc) where the margin is already smaller for Scubapro gear, and it allows them to have something at a lower price point to compete with internet retailers and cheaper brands. So I suspect some SP dealers will love it and others will hate it.
Personally, I suspect I will see a lot more Sub Gear regs on the service bench in a year or two as the shop will sell more at the lower price point and stiill be very happy as they will make up the difference in profit on the reg with the profit on service kits over the first few years - and not have to mess with the now fairly complicated free parts replacement program like they have to with SP regs.

I have yet to meet a knowledgeable Suunto owner with experience or comparison with other computers who did not dislike their Suunto as it was way too conservative compared to everything else in the water.
