I think getting a BC set up is a good idea. I used to be solely spinning and now the majority of my set ups are baitcasters. I wouldn't recommend switching your hands in your transition to casting gear. Stay with what's comfortable.
As far as your first baitcaster goes, I would recommend getting something with an aluminum frame and centrifugal brakes. A 1-peice aluminum frame is much more sturdy. I'm not sure what the Black Max has. I recommend centrifugal brakes because, in my opinion, it will be less frustrating to learn on. From my experience, learning on a baitcaster, my nasty backlashes would come at the beginning of the cast because I was not used to the touch/technique involved in the casting method. Centrifugal brakes affect the spool more in the beginning of the cast, when the spool is spinning the fastest. Magnetic brakes will affect the spool more towards the end of the cast. Now, I'm not bashing magnetic brakes. I just feel, from my experience, it will be easier to learn on centrifugal brakes.
Its not at Dick's, but I will recommend it anyways. I really like the Bass Pro Shops Pro Qualifier. It is on sale now at BPS for 80 bucks. Most will say that its a steal at retail price - 100 dollars. On sale, it is hard to find a better reel for the price. The reel not only has a 1 peice aluminum frame but it also has a dual braking system (both cent and mag brakes). I have 2 and I think they perform just as good as my other higher end reels. Then maybe take your discount and buy a rod and line or something like that at Dicks. Just my 2 cents.
