I used the Spectra Pro IV-A for the last 12 years, and what a great meter it is. However, unbeknownst to me at the time and completely out of the blue in the middle of a shoot, my light readings were coming in 1 1/2 to 2 stops over. Dallies were 2 days behind, so we didn't catch it until then. Getting a new light meter in the middle of the Mississippi river took another two days, but I finally spent the cash and sprung for the Sekonic L758-Cine.
I had no idea that the Sekonic meter was so advanced! With quick buttons to calculate wrattens and the ability to program your latitude toe and shoulders for each film stock took so much of the calculations off my mind. Obviously, the spot meter is a great addition too. Both meters are superb, but if you have the extra cash, I'd spring for the Sekonic.
If you are looking for a discount, try looking into the Friends of the ASC. I'm sure you'd find student discounts around as well. Hope this helps.
