Dubler Mic or Shure/Dynamic?

So I bought the software and opted not to do the Mic as I knew we had a Shure somewhere around here. Well, we don’t, so I asked if I could get a promo code as I bought the software a day before (it’s a tad cheaper with bundle), but no dice. So, now I’m wondering if I should go with another SM58 or if long-time users can vouch for the importance of the Dubler mic. Thoughts?

As a bundle it’s alright.
But without savings, I don’t think it’s worth it.
