Default 07 STi R180 Rear Diff carrier swap questions

I apologize if this has been asked an answered, my patience and google-foo aren't up to the task this morning (also need to actually do work today...)

So I bought I cusco R180 for my rear diff and was going to swap it in on my own. Had it tuned recently and the tuner made it sound pretty easy or maybe 'simple' is a better way to put it since easy != simple... skip to the end if you're not interested in the story to this point.

Anyway, I got to the point where the diff was hanging low enough to pull the rear cover off and realized that I'm retarded and don't have the tools and should have RTFM which clearly shows the steps and needed tools... So I put it all back together (there's nothing 'wrong' with the stock diff, I just wanted a better/real LSD - debate for another time)

Short story long - I took it to a shop and showed them what I wanted and they told me that I needed to have new bearings to go with it, and that removing the old bearings to put on the new diff was just not something they wanted to do - I got the impression they didn't think that removing the old bearings would result in reusable bearings. AFAIK there's nothing wrong with them, and I couldn't see any obvious reason why they couldn't be reused, but I don't work diffs for a living.

I'm annoyed and asking not so much because I think the guys wrong, but because I've had to wait almost 3 weeks now since getting the diff to get it put in. When I first got a hold of the shop, their guy was out with the flu, so I made an apt. for the following monday, showed up and the guy's kid was sick, so I grumbled and made an apt. for the next monday (today) where its revealed that I need bearings. Ordered bearings from subaru (who probably ordered the wrong ones given my recent luck), should be there thurs or fri. Which means next monday again...

So the question I really came to ask (aside from venting a bit) is did the bearings need to be replaced? I personally think they could be removed without damaging them and they just didn't want to do it. But they quoted me $275 to do the work - where another shop quoted me almost $800 and have excellent yelp reviews. I'm just tired of the back and forth. Since its just the carrier, they shouldn't need to set lashing and change shims and all that jazz in my inexperienced opinion so in my mind it shouldn't be this big a deal... or am I on crack?
